OK folks, I am a virgin when it comes to piranhas. I have had alot of fish, but from what I have read on this board it seems that piranhas are difficuklt to take care of. Currently I have 4 Pacus from 5-7" have had em for about a year with no troubles what so ever. I am thinking of ordering some .5" RB's from Aquascape. I would like some input help on what kind of tank, filter decor , etc. you guys would suggest. I am very excited about getting goin on these, but I know I just cant get a bowl and throw them in there when I get them. I will prolly just order 2 RB's for now. I would appreciate the help guys.
