I had 3 rb's together and one was killed already... and the other is on his way. Is it ok to have just one?

It's quite ok actually, piranhas don't really like each other so there's no reason they have to be kept together.

What size tank are you keeping them in and how often are you feeding? Alot of times one kills all the others because he's just an intolerant fish, but once in awhile there are environmental conditions that drive the fish to kill.

He will need much larger than a 29 to grow up happy when mature. Did you have all 3 in at the same time, or is he alone now?

i have a 4inch Lone rbp in my 33gal! Even though he is usually very skittish! Alot of members will agree that he will be more aggressive as he grows.

I have three 3" rbps in a 30 gallon now. They're doing great, no fin nips for 2-3 weeks.
They hang together and swim together against the current all the time.
But I guess this is more likely random, whether they tolerate eachother or not.
They will be moving soon though...

My red that grew up alone, when added into a 75 with a new p was the new guys bitch. So maybe when a rbp grows up alone they are wusses but in some instances he wont be, all depends on their personality.
