That Fish Place Aquariums and Fish Recap – Week of 8/24

Ah, Friday. Best day of the week! Though there is never a lack of interesting fish/aquarium/ocean related news to reinvigorate us and carry us through. Let’s take a look at the news and newbies!

  • Blue TunicateThe Grunion are running! AHHHHH! Actually, if you don’t know what grunion are and you’re concerned about why they are running, don’t worry, it’s actually a good thing. This might be something I would put on my bucket list of things to experience before I die. (I’m easily amused.) http://www.al.com/newsflash/index.ssf?/base/national-19/1250767015290200.xml&storylist=national&thispage=1
  • Of course I’d much rather be faced by thousands of little fish than have “Died of Toxic Algae Gases” imprinted on my death certificate. Visiting the French Coast is off my bucket list. Of course it will be something to reconsider if they get the situation under control in the next (hopefully) 50 years or so. http://news.bbc.co.uk/2/hi/europe/8195180.stm
  • Snooty WrasseIf anything could be more exciting than the running of the grunion, check out the image captured by Google earth!!! I always knew she was there somewhere, not even Nessie can escape the spying eyes in the sky! http://www.guardian.co.uk/theguardian/2009/aug/27/loch-ness-monster-google-earth
  • I can’t imagine that the guy in this article has much left on his list if he has one. Seems to me if he wants to do something he has little trouble accomplishing his goals. This guy is pretty amazing IMHO, but not just for his endurance, but for his guts at swimming in some of the rivers and conditions he has. We aquarists all know what lurks in the muddy depths, so this guy gets a big WOW “what a crazy-cool thing you did!” from me! http://www.usatoday.com/sports/2007-04-07-amazon-swim_N.htm
  • Spotted Pike Characin Everybody has an opinion on goldfish in the aquarium world, and sadly, the opinions are not always good. But when you see those bulging eyes and that bobbing, bulbous body, its hard not to smile. In case you didn’t know already goldfish do have some redeeming qualities, and they may be cause to consider them again as a new family pet. http://www.dailymail.co.uk/news/article-1209316/Gulp-Why-life-goldfish-bowl-lot-exciting-thought.html
  • There was an interesting article I read this week on the renewed interest of creating biotopes. I have always found the idea of setting up and maintaining a biotope interesting, and with all the new technology and advances in the aquarium world this is a better idea than ever! Biotopes are displays that are more true to nature, a little slice of a specific habitat and conditions with only plants and animals that are native to that habitat. These setups are a lot of fun to watch, and are great to reproduce for keeping specific fish in a habitat as close as possible to the one they’re found in naturally. I’m hoping that we can create one or two as retail displays in the future.

  • Whitebanded Pygmy WrasseWe get questions all the time from customers about something that emerged from their live rock or from a coral or from seemingly nowhere. Strange worms are often a fact of life in reef aquaria, and though you may not always see them, chances are there are some hiding away in the dim recesses of your rock. This little gem might help you ID or at least get closer to IDing the little surprises that come along with reefing.
  • Lots of you have pretty strong opinions, like we do, on bill HR669. Frank gives a recap of what’s going on with it now over on the Reptile Blog.
  • The biggest news in the retail store this week is the new plant gravel in our plant room. The plant gravel has been furnished by Seachem and will not only improve the appearance of the space, but hopefully benefit the plants for their short time in the room. Check it out to see all the colors of the new substrate in action if you’re considering a substrate change or a new planted aquarium.
  • New and exciting this week at TFP:

    Check the blog for pics of these guys.

  • I get excited any time we get Oxycheilinus sp., Cheilinus sp., and other similar wrasses. These fish are often overlooked and washed out in our pale tanks but they are real gems in the home aquarium with tons of personality and flashy color too. Check out the Snooty wrasses (How you can you not love something with a name like Snooty?) in stock this week, and watch of other similar wrasses like the Twospot Wrasse and Floral Wrasses periodically.
  • Cave BassWe got a Cave Bass this week! These guys aren’t available often but they are super neat. They’ll tend to hide out in shadowy caves in your tank, but you’ll be pleased just to know he’s there.
  • This little beauty, the White-banded Pygmy Wrasse, only gets to be about 2 inches long. A-dorable, and safe for the reef. Think nano reef or biotope!
  • People don’t often get excited about tunicates. Generally they look like a lump of putty or nothing much at all when they arrive, but the blue tunicate that arrived this week is quite a looker!
  • On the freshwater side, these Spotted Pike Characins are pretty eye catching. Not community friendly, but nice for the right tank!
  • African Oddities – the Bichirs and Reedfish

    Hello, Frank Indiviglio here. I have always favored fishes that seem to straddle the line between the fish and reptile/amphibian kingdoms. Included among these are both marine and freshwater forms, including the toadfish, frogfish, lizardfish, lungfish, mudskipper (note the common names!) and others. The freshwater fish family Polypteridae, containing the bichirs and the reed or rope fish, has long fascinated me and seems very popular with visitors to the exhibits I have worked on at the Maritime Aquarium (Norwalk, CT) and the Bronx Zoo.

    Few if any bichirs have been well-studied, and even the most commonly available species are rarely bred in captivity; much can be learned by the patient aquarist.

    Description

    The dorsal fin rays of these elongated, snake-like fishes are separated from one another, rising and falling in a series of humps and lending them the appearance of scaled-down dragons. This effect is most evident in the aptly named Senegal dragonfish (please see below). The pectoral fins are rimmed with fleshy lobes, and are paddle-like in shape and function.

    Swimming takes the form of short bursts, but mainly these fish scull along the bottom. The largest, including the commonly sold reedfish, can reach 3 ½ feet in length, but most are considerably smaller. Although dissimilar externally, bichirs are believed related to sturgeons, paddlefishes and gars.

    Range and Habitat

    Bichirs are limited in range to tropical Africa and the Nile River system, and are usually associated with shallow, plant-choked waters such as marshes, swamps and the shores of slow-moving rivers.

    Future Amphibians?

    The amphibian-like qualities of the bichirs are not limited to appearance alone. The swim bladder has evolved into an accessory breathing organ, allowing them to breathe atmospheric oxygen and to survive out of water for some time…few species are rumored to voluntarily leave the water for short periods. The young of some species even sport external gills, much like salamander larvae!

    Reed or Rope Fish, Erpetoichelys calabaricus

    This brown West African native has a sinuous, snake-like body and a wide mouth. The reedfish hides under the mud by day, emerging at night to feed upon insects, fishes, worms and frogs. It can reach a length of 3 ½ feet, but rarely attains that in captivity.

    Senegal Dragonfish or Cuvier’s Bichir, Polypterus senegalus

    Rounded, widely-separated dorsal fin rays lend the Senegal dragonfish an uncanny resemblance to its mythical namesake…it really does look like a miniature dragon!

    Senegal dragonfishes are distributed throughout the Congo Basin and reach 12 inches in length. They make hardy, interesting aquarium pets and often learn to anticipate feeding times. The effect of a large specimen in a well-planted aquarium is quite spectacular – they definitely deserve more attention from aquarists.

    Ornate Bichir, Polypterus ornatipinnis

    Swamps and marshes in West Africa are the home of this commonly imported bichir. Patterned with a lacework of black markings, the ornate bichir is one of the more attractive members of its family.

    Unfortunately, due to its unique appearance, the ornate bichir is often purchased on a whim. Few realize that the youngsters sold in pet stores eventually grow to 18 inches in length, and are often aggressive towards tank mates. However, properly accommodated ornate bichirs make fascinating pets, and, as they are rarely bred in captivity, are ideal species to study.

    Further Reading

    You can read more about bichirs, and see a list of all recognized species, at http://www.fishbase.com/NomenClature/ScientificNameSearchList.php?crit1_fieldname=SYNONYMS.SynGenus&crit1_fieldtype=CHAR&crit1_operator=EQUAL&crit1_value=polypterus&crit2_fieldname=SYNONYMS.SynSpecies&crit2_fieldtype=CHAR&crit2_operator=contains&crit2_value=&group=summary&backstep=-2.

    I’ll address captive care in more detail in the future. Until then, please write in with your questions and comments. Thanks, until next time, Frank Indiviglio.

    Aquarium Fish Growth Myths

    Eileen here. Some myths and legends are universal. Almost every country has some version of a “bigfoot” legend. Nessie is one of Scotland’s biggest celebrities. People are abducted by aliens and UFO’s are spotted in the sky around the world. What does the aquarium hobby contribute to this list?

     

    “Fish only grow to the size of their aquarium.”

    Like most of those other stories, this one likely started because people saw some truth behind it. They saw their fish grow large in relation to their aquarium, stop growing, then die. But, just like we now know that the Earth is not flat and we will not fall off the edge of it if we sail too far, we now know that the size of an aquarium does not dictate the size of a healthy adult fish.

    The most common victim of this theory is the  comet goldfish, the fish often sold as very inexpensive feeder fish or won in carnival ping-pong ball toss games. People win the fish or buy them as inexpensive pets, not knowing that the tiny fish they took home should be able to become an 8-10 inch adult with a lifespan of 10 years or more if well cared for. “Goldfish bowls” are sold almost everywhere that carries fish supplies. Small aquariums – 10 gallons or under – are often sold with pictures of small fancy goldfish on the box so it is no wonder that people may be unaware of the problems they are walking into.

    Keeping any animal, fish or otherwise, in a habitat that is too small for it causes a number of problems that might not be obvious at first. The fish people win at carnivals or purchase as small juveniles might be fine for a short time in a small aquarium, but as the fish grows, so does its requirements. Looking at the same situation in terms of a person instead of a fish, it becomes more obvious. An infant, for example, doesn’t require much space for his needs to be met. He can feed and exercise within the area of his nursery and regular cleanings can keep his nursery healthy. But, as the infant grows into a toddler, his needs also grow. He requires more space to exercise so his muscles develop properly. He is growing and needs more food and so produces more waste as a result that the same regular cleanings the infant received cannot control. As he grows through his life, that boy can certainly grow into a man if never let out of the nursery that he was kept in as an infant, but that man will not be as healthy as he could be. His hygiene and development will have suffered from being kept in a confined space and not allowed to flourish and develop properly and he will probably not live as long as a man whose environment has been allowed to grow with him.

    The same happens when a fish is kept in a small tank. As the body of the fish grows, so does the amount of waste it produces and the food it needs. This can affect the water quality of the aquarium and lead to disease caused by high ammonia levels, high nitrite levels, low dissolved oxygen content, low pH and other incorrect parameters. Just as a person kept in a small space cannot grow properly, the fish would also physically not be able to grow to its full size. Its body and skeletal structure may be stunted by the lack of space and ability to exercise and swim as it should, but the internal organs often continue to grow at a normal rate. The internal damage this causes, in combination with water quality issues, will lead to a premature death.

    While a small tank can certainly affect the size of the fish, it is not the way that we once believed. There is no internal sensor in a fish that can detect the size of its environment and adjust its growth accordingly. The fish we keep are  just as dependent upon us as small children to give them the proper care needed to keep them healthy so it is up to us to be aware of what their needs are and to do our best to make sure those needs are met throughout the fish’s life.

    That Fish Place Aquariums and Fish Recap – Week of 8/17

    Patty here, and welcome to our Friday recap. Lots of fun and interesting stuff crop up both worldwide and right here at TFP over a week’s time, so we’ve decided to start hooking you up with sweet updates on these kinds of things. Be sure to let us know what you think of these posts (The little thumbs up, thumbs down at the bottom), and feel free to send us some of the excellent things you’ve read in the comments or on Facebook.

    This week’s Noteworthy Fish stuff

  • I know that a little romancing can go a long way, but who knew that a little Barry White could push a cold fish into a passionate frenzy?! At the Sea Life London Aquarium, they’re doing what they can to set the mood for poor Zorro the Zebra Shark to woo the ladies. Good luck, little guy, everybody needs a little love! http://www.telegraph.co.uk/news/newstopics/howaboutthat/6054368/Barry-White-songs-used-to-encourage-shark-to-mate-in-aquarium.html
  • We already know the benefits of having live plants in the home aquarium, but it never hurts to say it again. I personally don’t think enough can be said about the benefits, and this article breaks it down in easy terms just to push the issue a little more. I mean, how would you like it if you were suddenly dumped in a bubble with only plastic trees and flowers? It would be like living on a Hollywood movie set! http://www.aquariumnews.com/only_browser/262411/
  • How lucky is this guy? I can’t say I don’t envy him! This beautiful behemoth seems to be just as fascinated by the diver as the diver is by him, so whatever he is doing to draw its attention is working, just watch out for flailing fins and tails. The amazing shots are definitely share-worthy. Sure, these are mammals and not fish, but still…. http://www.dailymail.co.uk/news/worldnews/article-1207590/The-underwater-dance-David-Goliath-Diver-perches-fin-friendly-50ft-humpback-whale.html
  • MACNA 21 is just a few short weeks away! The Marine & Aquarium Conference of North America (MACNA XXI) is being held in Atlantic City, NJ September 25-27, 2009. This is one of the biggest annual events for people in the industry and hobbyists alike. There are loads of exhibitors, awesome speakers scheduled raffles and tons of other fun to be had, drop the family at the shore and head to the Sheraton! Check out the homepage for full details! *Shameless plug* Your favorite Aquarium Supply store will be there too, so stop by and say hi to Dave.

  • Meanwhile, back at That Fish Place the most exciting project going on is the newly constructed Coral Propagation room. The room will soon be slowly populated with lots captive grown frags and in house cultured frags for future sale both in the retail store and online!
  • Our 700 Display got bright new bulbs this week and a few new fish additions. If you look closely at the rock it would appear that we’ve had a spawning , as there are numerous tiny new colonies of either Pocillopora or Seriatopora appearing all over the place! Stay tuned, they have to grow out a little to be sure.
  • The results of our first cross-Facebook/Fish Catalog photo contest are in, and Michael S. from McConnellsburg, PA is the winner with this sweet pic of a Black Misbar and a Derasa Clam. Michael will receive a $100 gift card, and have his photo featured in the Fall fish catalog. Check out Michael’s picture here, and if you’re interested in entering for the Winter Fish Catalog, send your high-res photo to petsonline@thatpetplace.com.
  • Cool new stuff at That Fish Place this week

  • Spanish ShawlYou can see where the Spanish Shawl Nudibranch gets its name, flamenco anyone? Very cool but they are specialized feeders like many other nudis!
  • Chestnut Cowries eat algae when their little, but may develop a taste for sponges and softies on the side as they mature, so keep that in mind!
  • This Hawaiian Cultured Blue Maxima is A-mazing!
  • Two species of microrasboras, very cute, very tiny, maybe worth a small species tank, but probably not fitting for the average community right now due to their small size.
  • Though I’m not nuts about crazy hybrid cichlids, this Red Dragon Flowerhorn is pretty eye catching.
  • Two sweet War Coral Frags…Get them while they’re here!
  • And from ORA, Extreme Misbar Ocellaris! No two are alike!
  • Just a sampling, come see us and check out these and tons of other cool stuff!

    Until next time,

    Patty

    Long Live the Queen Angel in Declining Caribbean Reefs?

    Melissa here. I recently read an interesting article (sadly, one of many) on the decline of Florida reefs.  The prognosis for the future of many Florida and Carribbean reefs is not looking good, especially if steps are not taken soon to stop the forces that are having such a negative impact on these environments. The reefs off the coast of Florida’s keys are in real danger, and according to this report, there has been a significant decline of both reefs and some fish populations in just the last 10 years. Snapper and grouper populations in particular have declined according to the article, and it is estimated that they are below sustainability levels. While I have been to Florida several times, I have yet to scuba dive there. I have been told by friends that it’s beautiful, and that wild queen angels (my favorite fish!) swim freely on these reefs. This article doesn’t address the Queen Angel population, but with their habitat being in trouble I wonder and worry about the impact on them over the next decade and beyond. I don’t know about you, but being an avid Queen Angelfish lover, I would love to take a trip to the Keys so I can take in the beauty of these reefs before it is too late. It may be sooner than we all think that this and other majestic species will only rarely be able to be observed, except in a captive aquarium environment. Feel free to let any thoughts you may have about the declining reefs and fish. Here is a link to the article if you want to read more:
