Question by Frank: 10 gal aquarium-what is a nice small cold water fish?
it sounds like goldfish really get things dirty quick and get too big to have that many in a 10 gal...im thinking that cold water fish may be more hearty than tropical....i would like to have at least 4, 5 fish...everyone has a different opinion about how much space a fish needs. thanks.

I have a 20 gallon tank and have 4 convict cichlids and a plecko in it. They all seem to get along pretty well and one of them even had babies not too long ago!
