Red-tailed sharks are very territorial with all types of fish. They do not tolerate their own kind, and will stake a couple of territories in the aquarium at the same time. Despite their name, they are not really sharks and actually belong to the minnow family. It is their upright dorsal fin that gives them a shark-like appearance.

While most fish tend to stay at a certain level of the aquarium, you will see your shark swimming at the bottom, middle and top of your tank. They are omnivores, which means they eat both plant and animal matter, including prepared foods, small live foods and certain vegetables. Sharks are active swimmers and need a large tank that is long rather than tall. A good rule of thumb is one gallon of water for every one inch of full-grown fish.

Common Name
Redtail Shark

Other Common Names
Redtail Black Shark

Scientific Name
Epalzeorhynchus bicolor


Feeding Habits
Fresh spinach, zucchini, lettuce and algae. Live brine shrimp, blood worms, glass worms and tubifex worms. Frozen vegetable diet, blood worms, brine shrimp, glass worms and plankton. All types of freeze dried and pelleted foods.

Thailand: Lots of areas to stake territories a must, use rocks driftwood and live plants for decoration.

The back edge of the dorsal fin forms a right angle on the female and the males ends in a point. Redtails have been bred in captivity, but the success rate is low due to their lack of intolerance for each other.

Additional Comments
Juveniles require a lot of vegetation in their diet , otherwise their body color fades and their growth is inhibited. Sensitive to nitrites in the water.

Rated 5 out of 5 by from Awesome fish I got my red tailed shark a month ago, and it is awesome. I bought a decoration for him that has two little places for him to swim through, he sometimes does laps. I also have non-agressive fish like guppies, and he never attacks or chases them.

Rated 5 out of 5 by from Awesome! I just bought one of these guys for my 20 gallon tank and he is not what I had expected at all. I had heard alot about how they are agressive and hide a lot but mine is really active and nice. He rarely goes in the driftwood I have for him. He looks really cool too! He does some other strange stuff too. Like when I go up very close to the tank, he swims right up to where I am! Its like he's saying hi. I guess some red-tailed sharks are territorial and hide alot, but I guess it depends on their personality. These fish are very hard to breed so if you try to breed them and it doesn't work, don't feel bad. I highly recomend these fish! But make sure you have a big tank, cause they can get big. I will have to move mine into a bigger tank soon. But don't stress out about not having a big enough tank for them, cause they take a while to grow. And lastly, don't get 2 of these sharks unless you have a huge tank cause they will fight for territory.

Rated 5 out of 5 by from Good fish I purchased a red tailed shark for my tank 2 days ago. He has been a great addition to my tank. He is very active and swims in all areas of the tank, however when he wants to hide I do have places for him to do so. He likes to munch on the plants in the tank, I would recommend to have real plants in the tank. I keep him with 3 X-ray tetras, 2 Dalmatian mollies, 2 clown loaches and 2 African dwarf frogs. I even catch him playing with the loaches. I was told that he would be okay with them, just not to keep him with any small fish, such as neons, guppies, glofish etc. Overall, great fish to have and very pretty to look at as well.

Rated 5 out of 5 by from Awesome Fish! I have a male redtail shark and he is the easiest fish in the tank! He is not aggressive at all and is super easy to take care of! Would definitely recommend this fish to anyone and would be easy enough for beginners!

Rated 5 out of 5 by from Awesome! I have this awesome fish in my 55g tank. He resembles a Stealth Bomber or some type of missile when he swims, very cool to watch. Mine is very active and doesn't really hide, nor does he bother any of his tankmates. Great addition to my tank and can't wait to watch him grow to his full potential!

Rated 5 out of 5 by from great fish, territorial This is a very beautiful fish, mine changes colors depending on his mood. When he is stressed or agitated he is a very light gray, when he is happy he turns dark black with bright red/orange fins. He is supper territorial. I bought him a cave that he loves (he won’t leave the thing) when a fish comes close he quickly launches into attack mode, no biting, just aggressive swimming. He mainly feeds at the bottom and stays on the bottom in his cave. On occasion I’ve seen him mid to high level “exploring.” Keep in mind that he is very territorial, don’t get multiples these or other cave dwelling fish as they will fight over the caves. Other than that, they are beautiful fish.

Rated 5 out of 5 by from Great fish I bought this fish relatively small (about 1 inch). He is by far the smallest fish in my tank, but gets along great with 2 featherfin catfish a dwarf gourami and a sailfin molly. He is very active, he swims around with my DG and molly. Borys likes to go in my cave and likes his hiding places so make sure to have some places for your shark to hide. It's important for them to feel secure. Overall, awesome fish!

Rated 5 out of 5 by from Awesome Colours I love my Red Tail Shark. This fish is so unbelievable, his colours are awesome! I feed him tropical flakes that are colour enhancing and it has really turned him jet black on his body and made his tail blood red. I keep him with 3 Electric Yellow Cichlids and they get along so well. For the most part, he spends his time near the bottom of the tank, resting under the rock caves I bought him but he sometimes swims around the middle of the tank. He also goes up and down the glass and all around the rocks feeding on any algae he can find. He loves it when I feed him chopped romaine lettuce and brine shrimp. Overall he is an awesome fish and I would definately recommend him.
