That Fish Blog – Aquarium Advice and Information

Hey everyone, Sam here. Nano tanks are a really popular trend in the aquarium hobby.  The first tank that I’ve ever owned was a 20 high.  Since then, I’ve continued to go smaller and smaller, with each endeavor ( to a 10 gallon then a 2.5 gallon).  Nano tanks are fun and can be set up almost anywhere!  Smaller tanks are cheaper to set up, but not necessarily easier to take care of, especially when you have a busy schedule. 

One of my favorite fish in the aquarium hobby is the Yasha-Haze Goby (Stonogobiops yasha).  The Yasha-Haze Goby is a small fish that only gets about 2 inches long.  It is white with red stripes going down the sides and yellow translucent fins. Magnificent!  It has a very large first dorsal ray, which extends over an inch high.  The goby feeds on small meaty foods such as mysis shrimp or copepods.  In a well established tank, it will be able to find a good food supply just from copepods, but regular feeding will keep it in great health.  The Yasha-Haze Goby has an interesting behavior of paring up with a small pistol shrimp.  The pistol shrimp will help dig a burrow while the goby stands guard.  Once the burrow is dug, the pistol shrimp will hide down in the burrow and the goby will swim right outside of the burrow.  The shrimp will keep one of its antenna on the goby and if there is any sign of trouble the shrimp will know instantly and retreat further back into the burrow.  In return for building the burrow, the goby will gather food and bring it to the shrimp.  The best shrimp to use is the Randall’s Pistol Shrimp (Alpheus randalli).  These both work great in small tanks and are awesome as the primary occupants of a nano tank!

Both of these animals are interesting in their own respect, but when paired up they can become an amazing sight to watch.  The key to helping these animals pair up if they are not purchased together is patience.  Allow them time to find each other and set up a burrow.  If they are not disturbed during this time, the patience will be rewarded ten fold as you watch them interact together in one of the most interesting ways. 

 Best of luck,

Sam

Hello, Jason here. Over the years the aquarium trade has progressed to cater to the demands of consumers and to comply with the prevalent eco-issues at the same time.  Now more than ever, consideration is also given to the impact the trade has on native populations and the integrity of  stock. The livestock in the aquarium trade is increasingly supplied by breeders captive bred or captive raised fish.  Some fish are bred for color, behaviors or another reason that makes them unique and interesting to the potential buyer. While this is good as it helps protect wild populations from being over harvested, it does bring up another problem that appears within the aquarium trade from time to time. Breeders are constantly trying to keep up with the growing demand for fish, so their methods may not always produce the best quality of fish. This is often most noticeable among Cichlids, especially African Cichlids, though some of the better known hybrids commercially available are derived from New World Cichlids.

Some breeders are more concerned with quantity and saleability that the integrity and quality of the fish they are producing for the trade. Hybrid fish result when two distinct species produce offspring together, sharing qualities of both species. Fish with physiological deformities may result as with Bloody Parrots, but at the very least, captive hybridization can obscure or pollute pure genetic lines that should be kept pure, from a conservation stand point.  Defects can be small like an abnormal color pattern or body shape, or more advanced. Many hybrids will look very similar to one of the two species that it came from, but it may have unique coloration or slightly different shape. Some of these hybrid fish may never show any sign of distress as a result of their questionable lineage. Some hybrid fish are born sterile.  Fish of poor breeding like this may have issues surviving or thriving in the aquarium.  They may have trouble feeding or swimming, especially with tankmates that do not have similar disadvantages.  If they do have a defect that is enough to effect these abilies, they will not have the ability to thrive without special attention in many cases. Some hybrids may also have difficulty in fending off disease.

Some breeders choose to selectively breed species, typically to develop or reproduce a specific mutation that occurs within a species, but is not found in the wild.  These are often carefully bred for a specific result such as elongated fins or to enhance a particular color that some fish bear naturally to some degree.  These fish still maintain their species integrity, but display more prominently the desired trait they were selected for.  True conservationists may shy away even from these selectively bred variants to maintain the most naturalistic display possible, though color variants are usually more acceptable than hybrid fish.

Keep quality in mind when looking for a new fish for your aquarium. Reputable breeders take pride in the fish they produce, and are careful to breed good stock, with pure lines to preserve the integrity of the species they are helping to conserve.  There are many breeders that selectively breed purebred strains that have brighter coloration and better health because the species lines are kept pure. These are the fish you want to look for to keep in your aquarium.

Until next time,

Jason

Cory here. I thought I’d take my next few blogs to go over the “ins and outs” of Nudibranches. Like lots of organisms living in an aquatic system, these interesting creatures bring a host of features to your saltwater tank. And, along with the good, it’s important to point out the bad…and the down right ugly things about nubibranches in your aquarium too.

The Bad:

Nudibranches target Montipora, Zoanthids, and Softies

There are so many coral eating organisms, Butterflies and Angelfish are the obvious ones. However, some of the worst pests are ones that you can barely see. Flatworms and Red bugs are most notorious for destroying Acropora species. However, Montipora species have their own pest: a Nudibranch.

They are hard to see, especially if you do not know what you are looking for. The largest I have seen was a half centimeter in length, tucked behind a crevice in the coral. They are always near a piece of the coral that is in the process of dying. This particular nudibranch feeds only on Montipora tissues, more commonly the plating varieties such as Montipora capricornis. They lay their eggs in a spiral or cluster, on the underside of the coral. Usually hatching within a few days, depending on water conditions, they immediately begin munching on the coral tissue. A couple adult Nudibranches can easily consume a one inch frag in 24 hours.

There isn’t a simple way to eradicate them. Dipping the corals in a Lugols Iodine or Tropic Marin Pro Coral Cure solution will help to loosen the nudibranches, so they can be extracted. The dip however, will not kill the egg mass. The eggs must be removed immediately using a scraper, toothpick, or a toothbrush. Any portion of the coral that has died or seems to be infected should be cut off just in case there are eggs imbedded in the skeleton.

Nudibranches are also commonly found feasting on Zoanthid polyps. These particular types of Nudibranches are especially hard to find because they look very much like the polyp that they are eating, even matching the color in most cases. Zoanthids commonly close and stay closed for days, eventually polyps begin to disappear. This is usually the first sign of infection. Again, like the Montipora Nudibranches, dips will only remove the adults, leaving the eggs behind. The eggs are usually laid on the underside of the poylps, but can also be found on the rock itself.

Soft corals have many different species of Nudibranches that prey on their tissues. Some are extremely large and colorful, while others camouflage themselves, making detection extremely difficult. Like other corals, removing the adults with coral dips and manually removing the eggs when possible is the only effective way.

There are so many species of Nudibranches in the oceans, many found on the Reef and serving some purpose good or bad. We are learning more each and everyday about Nudibranches, what they eat and where they come from. We are importing corals from around the world, in some cases from areas we have never collected before. With new locations, comes new pests and most likely new Nudibranch species, good and bad.

Check back soon for the next part of this article.

Happy Thanksgiving!

Hey readers, Dave here. It has been a busy couple of weeks here at TFP leading up to the holiday season.  It has been especially busy for me, as the top of my to-do list suddenly changed to repairing the touch tank.  Originally installed in 2002 (as somewhat of an experiment), the Marineland Touch Tank was in dire need of a makeover.

After many patches and repairs over the years, the old tank liner finally had so many holes in it that it could no longer hold water.  The liner needed to be replaced!  For anyone who has ever replaced the liner in their pond, you know what an ordeal that can be.  We found a temporary home for our touch tank celebrities, and jumped into the physical mess of getting the old liner out, including removing the hundreds of pounds of rock and substrate. Luckily, we are out of pond season here in Lancaster, so we had the advantage of being able to convert one of our Koi holding systems to saltwater, as a temporary house for our touch tank buddies,  while their home is being renovated. Next we’ll be getting the newer, more flexible liner installed and getting all the animals back home! It’s a whole lot going on, in a short amount of time.

Many, many people (both local and distant) visit the store, in part to see the stingrays and other creatures in the display.  There has been a parade of sad faces come around the corner, expecting to see their touch tank friends, but finding destruction in stead.  Never fear, the rebuild will only take a few more days, and the touch tank will be better than ever!  Along with the new liner, there are also some filter upgrades taking place behind the scenes.  We are truly sorry about the down time for the touch tank, this is the first time we have closed it since it opened seven years ago.

Stop in soon and see the stingrays in their newly renovated home.

Thanks,

Dave

Hello everyone, Craig here,  and I have to admit something… I LOVE catfish.  Big and clunky, or little and petite, doesn’t much matter. I just love catfish! We’ve been getting some pretty amazing catfish in lately, and I wanted to just highlight some of the crazy species we see here from time to time.

Let me start with Brochis multiradiatus, otherwise known as the Hog-nosed Brochis cat.  Not exactly a Corydoras cat, this larger cousin of the Cory’s has a lot of character. These big fellas are about 4 inches long and they are like vacuum cleaners at the bottom of your aquarium! They are brown to grey with a metallic green overlay, and elongated, pig-like noses. These cats are not as commonly seen as their little cousins the Corydoras. Hog- nosed Brochis cats have always proven to be sturdy and hard working residents in community and semi-aggressive community aquariums.

Want something weird? Well, the first time I saw the Spoon-faced Whiptail, I was practically speechless. The bizarre body structure of Planiloricaria cryptodon has to make it one of the strangest looking fish of the catfish in the world. With a head that is flat and round, these guys really do live up to their common moniker of Spoon-faced Cat. To make them even more interesting, they have very long tail filaments that can easily be as long as their bodies. They get rather large, growing up to a little over 8 inches, but they are very effective scavengers. In an aquarium with soft, fine substrate these cats will crawl around the bottom and suck up any left-over foods that might have settled there. Totally strange, but hard working, too.

Next on the list is the Spatula-barbeled Catfish, Phyllonemus typus. These small catfish from Lake Tanganyika are something really special. Their coloration is silky brown with a white belly, and they have long, thin barbels that each end in a flattened, feathery black tip. I can remember seeing these fish in books when I was younger and wondering what they looked like in person… well, I gotta say, they are even more beautiful than in the book, in my opinion.

Perhaps the star of the current list of catfishes we have in stock is the Starlight Bristle-nose Catfish, Ancistrus dolichopterus, or L-183.  A stunning and somewhat new addition to the world of plecos, the Starlight Pleco has dark coloration with tiny white speckles covering the front half of its body. The edges of its tail and dorsal fin are a bluish-white color. These are highly prized by breeders and collectors. These plecos only attain a size of about 4 inches. I can see how some people are absolute fanatics about this fish.

The selection of catfish in our fish room is constantly changing. These listed above barely even scratch the surface of the interesting and beautiful species available in the market. Anybody out there have a favorite catfish species to tell us about? It is kind of like being able to live out a personal fantasy, being able to order and see these amazing fish every day! If you’re ever interested in these or any other catfish we have available, or if you have any questions we can answer, please feel free to comment below or stop in and take a look for yourself.  

Thanks, Until next time,

 Craig
