I have just put in a Red Tailed Black Shark in my tank. I have been made aware taht these fellas are little hooligans. Mine seems alright, I have watched him and he seems to keep himself to himself. he is only about 2 inches long at the moment. Someone has mentioned that If I put in Bolivian Rams he might take them out (been watching to much TV I fear).I have noticed the shark chase my Lemom tetra one or twice, but only when they bump off him first, only for a few seconds and only chasing.
Will it really harm other fish.
I would really like to put in a couple of Bolivian Rams, how much of a problem do you people think this would be.
