I have 6 goldfish and a couple baby crayfish in an uheated 55 gal. tank. I want to know what else could be in there that won't mess with the goldfish. The crayfish will be coming out of there soon since they are getting bigger. I read an article in Aquarium USA that cory cats and some tetra can be in unheated tanks and sometimes do better in cooler tanks. Also, livebearers which are wild caught. Anyone have any feedback on this or know of any other fish I could add to this tank, I would appreciate it.
thanks,
