have decided to set up one of my 40 gallon breeders for my goldfish. we have 4 fancy goldfish, 2 of them are about 3.5" and 2 about 1.5", two are nromal fat fancy goldfish, one has big eyes and the other has bumpy stuff on his head. i will be using a penguin 350 for filtration. is there anything else i should get or do for the goldfish or does it sound like i'm good to go?
