hey i am getting a gold piranha, i have a big enough tank for one but i was concerened how aggresive they are on a scale from one to ten? i heard like a seven but just wanted to get everyones opinion. thanks
I raised one in a 30 gallon for about a year (got 4.5" sl) and put it in my 60 gallon planted, didn't like it so it went back into the 30 and was happy
