Gem Tang Tank Setup

Although it is important for your gem tang to have many places to hide, you do not want to crowd your tank. Gem tangs are very lively swimmers and need plenty of free space. The main goal is to provide your fish with everything it needs so its stress level will be as slow as possible. It is already stressful to be placed in a brand new environment. You want your gem tang to be as stress free as possible to avoid health problems.

Gem Tang Food & Diet

Gem tangs are herbivores. They can be fed by adding live rocks for your gem tang to graze over. However, if you have another herbivore in the tank you are going to need to do a little more. Gem tangs eat broccoli, zucchini, and nori.

Gem tang feed throughout the day. Make sure you feed them more than once a day, keeping a sharp eye out for any health issues. If your gem tang starts showing signs of sickness, one cause may be a lack of nutrition. It is also acceptable and recommended to add some meat to your fish’s diet. Even herbivores need all the nutrition they can get. Shrimp and brine are excellent for this. Proper diet will strengthen the immune system of your gem tang and possibly reduce aggression.

Breeding Gem Tang

Breeding gem tangs is not an easy task. It’s a lot of work to take care of just one of these beautiful fish. Male and female gem tangs are almost impossible to tell apart. This is one of the reasons that breeding may be harder than one may think. Another reason is that, in the wild, male and female gem tangs release their eggs and sperms onto the surface of the water. A tank, no matter how big it may appear to the owner, is not an ideal place for this to occur. As a matter of fact, no one has ever bred gem tangs in a tank of any kind. Gem tangs are not the right choice if you plan to start a simple fish breeding operation.

Gem tangs typically do not like each other, however, gem tangs are compatible with many other fish.

Fish that can live in the same tank as a gem tang include: assessors, dartfish, gobies, and blennies. Fish with a similar shape as the gem tangs will more than likely not be welcome into your tank. Gem tangs do not like any fish that looks like another gem tang. It is good to note that gem tangs are not compatible with purple tangs or with any other fish in the zebrasoma genus. It is very important to know what fish your gem tang will accept and which ones they will more than likely fight. Fish that do not live well with gem tangs include: the batfish, rabbitfish, pipefish, triggerfish, and seahorses. Fish that share similar diets should not be put in the same tank as your gem tang. As a result of this, one of them will more than likely starve to death.

Gem Tang Disease

If you are going to take on the responsibility of being the owner of one of these fine creatures, you must be aware of the warning signs to watch out for. Signs your gem tang in not feeling well include: odd swimming or lack of swimming, lack of eating, torn fins or new spots on their bodies. Be aware that if you own a juvenile, their physical appearance will change as they get older. Pay special attention to their behavior and eating habits if you suspect new spots are not normal in color. The groups of diseases to look out for are as such: environmental diseases, nutritional diseases, social problems, and trauma.  Environmental diseases can be caused by too much heat or not enough heat possibly due to the aquarium lamp being on too long or too short of a time. Nutritional diseases can be avoided by assuring your fish has enough food and is given the proper, recommended amount. If your fish does not have proper greens and even meat, it can develop a nutritional issue. Social diseases can occur if your fish is being bullied or physically injured by other fish. This is why it is crucial to be aware of the fish that should and should not be put in with your gem tang. Gem tangs are prone to something called marine itch. It is very important to make sure your fish gets proper treatment and care from an expert if this occurs. Proper and prompt care will more than likely prevent further problems.
