well actually the Aquaclear 500 is form my 55 gallon and the 2 penguin 150's are from my 30 gallon. All the filters have been in use for over 2 months so I decided to let it cycle for just about 12 hours and then put the fish in since the filters already had so much beneficial bacteria built up in them.
Also yeah the oher fish in there are 4 male convicts from my other tank. I gave my friend 2 females and he gave me to males. So that i wouldnt have any breeding so the convicts wont be to aggresive.
