I've had my red tailed black shark for about 3 months. It has been fine so far, though now its getting bigger as I bought it from when it was young, I find it is a bit more territorial with the cave. It will nibble at fish that comes in the cave and then leave them alone when the leave. Over all there very good cleaners of the tank with algae and un eaten food at the bottom. A must have for any tropical aquarium, but I would only have 1 in a tank. To aggressive towards own kind I think.

MD, my red-tailed black shark, is about as cute as they come. When the sun comes out he lay down on the rocks and sun-bath, then when he's had his fill, he'll chase my dwarf puffers around and finally end the day by eating out of my hand! Life would be boring with his personality!

Dude, I've got a Red-tailed in one of my 6 tanks and it's dope to watch him dart in and out of his cave. I've got him to except flake food too.

I have about a 55 thank with 3 clown loaches, 4 bala sharks and my favorite of them all a red tail shark. He is real Black and the tail a deep black. Before I added the bala sharks, he will just roam about and play with the loaches. Once I added the bala sharks he went crazy. He is always chasing these guys around and picking on them. They are a fun bunch to watch. The tank is very lively now. The only thing is I wonder if he is playing with them or biting them. He is a riot and I love that fish so much!

When I first got some red tails one of them kept driving the other ones to hiding I thought he was punk but when I turned out the light the others would come out and the big one wouldn't chase and scare them as much but when the light is on he is a bastard.

My Red Tailed Black Shark is still only around an inch in length and likes to chase my Black Phantom Tetra around but not aggressive at all. Quite amusing to watch. He also hangs with his head toward the water by my filter ! Bit like a catfish. Must enjoy the air bubbles !

I had one of these sharks and was told by the fish guy at the store that is was peaceful. Much to my dismay I discovered this must have been a lie because as soon as he was bigger than a fish he killed and ate yes actually ate them. Be VERY cautious when buying these fish e sure to select a peaceful looking one.

We have a beautiful 72 gal bow front tank with seven redtails in it, a clown barb that was sold to us as a clown loach before we knew what they looked like, two zebra danios, ten blue-finned danios, six Panda corydoras', a common pleco, and a Golden Nugget. Oh, and tons of driftwood and live plants. The sharks are beautiful to watch: they each have staked out their own part of the tank and will defend it if necessary, even the littlest one, who's only about two inches, against all others, even the dominant 4" female. If you're considering getting sharks, I highly recommend >a lot< of research first. They are aggressive and will kill other fish if they intrude within their territory or get caught in the crossfire of the feeding frenzy. We've lost a few long-finned danios because they can't swim fast enough. One of the remaining ones is missing an eye. I'm beginning to doubt the wisdom of having the danios in there at all, since they vie for position for the live food. Anyway, avid shark lover. I just don't want people to misunderstand what the little buggers are capable of.

My red tailed black shark was aggressive towards all the other fish - danios and even a fairly large clown loach, until I moved her into a bigger tank (36 inches). Now she seems calm and happy.
