Hi, I was looking for some information on rasing piranah's. I'm a college student living with 1 roommate in an apartment. We have a relatively quiet apartment. The reason I'm posting is because I can't really find any information on actually rasing the piranah's. I want to get a killer fish (aka one that eats other animals), but it needs to be relatively cheap to setup (under 100$). I already have the tank, but thats about it. I haven't been able to find anything on setting up the tank, how to raise them, their diets, how many fish per size of tank, etc. If anyone has any tips, please help me out. Thanks!
