last week i got a red tailed catfish and it has eaten 3 guppys, 1 molly, and one silver shark (ggrrr) it has left my red tailed shark and i have bought a red siamese fiter fish - but im not so sure i will have that by the end of the day as the catfish is watching it closely! so i have a catfish and a shark - my tank looks so empty! what can i have with a red tailed catfish and that it wont eat?

Especially when they are sold so cheaply and so small. I do lay a lot of blame on shops that stock these fish (together with similar such fish). Because in reality, how many people that frequent lfs's have tanks the size of a pond in their house ?
