Introduction to Triggerfish

Welcome back Mellisa, I hope that you enjoy this general article about Triggerfish. These are facinating, beautiful, and fun fish to keep in your marine aquarium.

Triggerfish

Triggers are with out a doubt some of the most aggressive saltwater fish available to hobbiest. They are carnivores and will eat any small tank-mates. Triggers usually aren’t very picky when it comes to food. They should be fed shrimp, scallops, krill as well as meaty pellets. Triggers should be housed in a large tank 100 gal or more. Larger wrasses, groupers, eels, and large angels are acceptable tank-mates. Most triggers are not reef safe and will chomp on corals, eat crustaceans, as well redecorate the tank upsetting corals and live rock. Use extreme care when placing heaters and power head cords inside the tank. Triggers tend to be very curious and may nibble on the cord causing harm to themselves as well as other tank mates. An aquarist must use caution when working in the tank to avoid being bitten.


In the store we sell several different species of triggers. Some are very aggressive and should be kept alone while others are fairly docile and may be kept in a reef tank with caution.

One of my favorite triggers is the Queen trigger (Balistes vetula). What can I say, I love my queens (Queen angels and Queen triggers). Queen triggers are gorgeous but don’t let their attractiveness fool you. They are very aggressive and get very large which may be part of the reason this fish is not seen all that often in the trade.

The Fuscus trigger (Pseudobalistes fusco), Clown trigger (Balistoides conspicillum), and Undulated trigger (Balistoides undulatus) are also very aggressive triggers but are commonly seen in the trade. These triggers are very attractive and will add character to any predatory tank, just make sure other tank-mates are established and will be tough enough to hold their own.

There are a few triggers that are considered “reef safe” with caution since they are mainly planktivorous. While these “reef safe” triggers do not eat coral, they will most likely eat hermit crabs and shrimp, so be prepared for this behavior if you try them in your reef.

Some triggers in this category include Blue Jaw triggers (Xanthichthys auromarginatus), Sargassum triggers (Xanthichthys ringens), Pink Tail triggers (Melichthys vidula) and Niger triggers. These triggers appear to be less aggressive and are commonly seen in the trade.

Brackish Water Aquarium Basics

One of the aquarium topics that seems to create a great deal of confusion amongst our customers is what is a brackish aquarium, and what do you need to successfully keep brackish fish. To shed some light upon this niche of aquarium keeping, I would like to welcome Lexi Jones back to our blog, to share this article about brackish aquarium basics that she has written.
Welcome Lexi!
You might ask, “What is brackish water?”

Brackish water is a mix of freshwater and saltwater, as in estuaries, mangrove swamps, or brackish rivers. The salinity is higher than freshwater, but less than salt water. The specific gravity should be kept between 1.005 and 1.015 for a brackish water aquarium, depending on the type of habitat. You may have to increase the salinity of the water over the fish’s lifespan; this also depends on the type of fish you plan to keep.
Owning a brackish water aquarium is very unique. It is also easier to keep than a saltwater aquarium, being that the fishes in these habitats are used to fluctuations in salinity and water parameters.

The basic supplies you will need to start a brackish water aquarium are as follows:

Aquarium– Brackish aquariums can be set up in just about any size aquarium, I would start with at least a ten gallon size. As with any fish that you plan to keep in an aquarium, you should know the adult size of the fish, and make sure that you have chosen an appropriate match for the size aquarium you have.
Filter– Hang on the back bio-wheel and mechanical power filters, or canister type filters are the best types for a starter brackish water aquarium.
Substrate– sand. This can be any saltwater aragonite sand or even children’s play sand. This sand will help to stabilize the pH of the aquarium, which should be between 7.6 and 8.4 depending on the type of habitat.
Heater– The temperature should be about 80- 82 degrees Fahrenheit. You need to make sure the heater is adequate in size. A rule of thumb is 5 watts of heat per gallon. You will also need a thermometer to make sure the temperature stays constant.
Any tank should have a Glass top or hood. Brackish water aquariums will evaporate water faster than most freshwater aquariums, given the higher temperature recommended. The use of a hood will help to reduce evaporation as much as possible.
Lighting is another requirement, but how much you need varies. If you are only keeping fish, a simple fluorescent bulb fixture will suffice. However, if you plan on keeping plants more intense lighting is required. Also, the light should only be on for around 10 hours a day.
Marine Salt– I use Instant Ocean at home, but any brand of marine salt will work. DO NOT use freshwater aquarium salt; this is not the correct salt to use for brackish or marine tanks.
Hydrometer or Refractometer Hydrometers and refractometers are devices that measure the salinity and/or specific gravity of your aquarium water, and allow you to make sure that you are maintaining the proper salt levels in your brackish aquarium
Water Conditioner– This will remove chlorine and chloramines that are in tap water. Prime and AmQuel are both good water conditioner products to use.
Bacterial Supplement– Products such as Stress Zyme, Stability, or Cycle add beneficial bacteria to the aquarium. The bacteria in these products help to jump-start the aquarium by breaking down organic waste. It may take up to 6 weeks to start a large aquarium. For more information look up Cycling an Aquarium.

The lighter Side of the Aquarium

Anyone who has spent much time around That Fish Place knows that one of the things we try to do is to not take ourselves too seriously, and to try and have a little fun with our work. So, in the spirit of having a little fun, here are some stupid fish jokes. (and please, if you have some of your own post them in a comment, and we can expand the list)

What did the trout say when it hit a wall?
Dam!

Why did the whale cross the road?
To get to the other tide.

Why didn’t the lobster share his toys with his friends?
He was too shellfish

Where do shellfish go to borrow money?
To the prawn broker!

What’s the difference between a fish and a piano?
You can’t tuna fish!

Species Profile: Long Horn Cowfish

Welcome back Melissa! Enjoy her profile on the Long Horn Cowfish, or Lactoria cornuta.
Cowfish are very cute curious fish. Who couldn’t love a bright yellow box shaped fish with whitish blue spots and little horns sticking out from its head and behind its caudle fin?? Cowfish are very friendly and have great personalities. They are generally peaceful and get along with other peaceful fish like chromis, anthias, and basslets. They may eat small inverts as well as graze on live rock, and pick at algae from time to time. In captivity, they usually accept brine shrimp, mysis shrimp, krill, as well as other frozen foods. They should be fed small portions several times a day. With frequent feedings water quality must be continual”Long Horn Cowfishly monitored. It is a good idea to only house one cow fish per aquarium since they are aggressive towards their own species. A single cowfish should have at least 100gal since adults can reach a max size of 18”. If cared for properly they can live in an aquarium for many years.
Cowfish, as well as other members in the box fish family, are able to produce an ostracitoxin which is found in the mucous secretions in their skin. However, the cowfish must be alive to to release this toxin. They only appear to excrete the toxin if they are stressed or feel threatened. Cleaner shrimp and fishes that feed on the slime coat of other fish should be avoided as tankmates because they may provoke the cow fish to release its toxin. If the toxin is released in a closed system the water will usually have a milky haze and the fish immediately start gasping. It would only take a matter of minutes to kill the cowfish as well as the rest of its tankmates. Inverts tend to withstand higher concentrations of the toxin than fish and are more likely to survive. If you suspect the toxin is in your tank, add fresh carbon immediately. If carbon is used and replaced regularly you may see little to no effects of the toxin.

Cowfish are a unique and interesting fish. They may not have soft cuddly fur but they are as close as you can get to an underwater puppy dog!

Species Profile: Splendid Dottyback

I would like to welcome back Melissa Leiter, One of our staff Marine Biologists here at That Fish Place. Melissa has a species profile for one of the thousands of fish here in our fish room.

Welcome Melissa,


The Splendid dottyback, Pseudochromis splendens, is a spectacular fish with its bluish gray stripped body and brilliant yellow tail. They tend to be bullies or down right nasty if they are housed with smaller docile fish. They do best if kept with other larger semi-aggressive fish in a large tank, or kept by themselves in a smaller tank. They definitely don’t need “friends” to be happy.

Something cool about dottybacks in general, including the splendid dottyback, is that they are all hermaphrodites meaning theoretically if you add 2 of the same species you should get a male female pair as long as they don’t kill each in the process of deciding dominance. Splendid dottybacks adjust to captive life very well, and in fact, are one of the few marine fish species that have been succesfully raised in captivity. Splendid Dottybacks will accept many foods including mysis shrimp, brine shrimp, formula 1, formula 2, even flakes and pellets. They are far from “picky” eaters.

They may also hunt down and eat those annoying bristle worms and flat worms to keep those populations under control. So if you are looking for a small hard headed fish that has the attitude of an angry trigger from time to time then the splendid dottyback is the fish for you!

Thanks Melissa, Psuedochromis are one of my favorite types of marine fish. They have alot of attitude in a little package, and are alot of fun to keep.

Until next blog,
