So true. There's alot of gray areas in that theory especially with piranhas considering they are not a schooling fish in the true sense. They need room to get away from each other.Xenon said:I am with Grosse, a lot of people say it is 20g a fish regardless but I dont subscribe to that theory. You should be fine with that amount of fish in there until 6 inches or so. It will be fine for the first 6-8 months you have your fish (possibly a year).
I have two pleco's with my reds for 9 months, and they're fine (they earned their place in the tank through a number of fin nips ). Besides that, I keep 4 spotted and 2 striped talking catfish, which are perfectly safe, because they're nocturnal, and hide as long as the p's are active.RAZORTEETH said:new to the piranha scene and i have a question what kind of scavenger fish can be used to keep the bottom of the tank clean without being eaten?
