i have absolutely no idea. why would someone keep piranhas? no offense. they are kind of cool
How many gallon tank do you have? How much is multiple? And what kind of fish? The bigger the tank the better. The more territories the better and if it is community fish the better. Not 100% they are all going to live in perfect condition's.
IN WATER!!!! (TANK!!)
it cleans the tank and keep the fish heathy
Well it depends on the fish kind. If you happen to find a fish in the water such as... Pond,lake,river, ocean you may want to keep them in difrent tanks... Because i got one of though and they ate eachother... But otherwise yes you can put them in the same tank
Not unless you had another fish in there.
