Red Tailed Black Shark



Red Tailed Black Shark, Epalzeorhynchos  bicolorThe Red Tailed Black Shark originally came from Thailand.  The body is black with a distinctive red tail.  The black color can fade when the fish is distressed.  They are aggressive and intolerant of their own kind.  Red Tails live at the bottom of the tank and establish a territory among plants.  Make sure the tank is covered though, as they are jumpers.  The other community fish should be of similar or larger size and able to defend themselves.  If more than one Red Tailed Shark is kept in an aquarium, hiding places are a necessity and a group of 3 or 4 Red Tails should be maintained - this is not recommended.  Breeding is extremely difficult due to the intolerance of these fish for themselves.

Fred McFetters - I found out you canít keep Red Tailed Black Shark (RTS) and a Rainbow shark together, they fought like crazy until I put the rainbow in another tank. My fish tank with 5 bala sharks and the RTS is a happy place. The Red Tail lives in his rock cave, and makes his rounds a couple times a day where the bala sharks swim back and forth all day long.
