can goldfish and tropical fish live together
Goldfish and tropical fish can definitely NOT LIVE TOGETHER! It is a HUGE mistake to put goldfish with tropical fish. 1. The temperature! Tropical fish live in higher temperatures than goldfish, and you don't want your poor coldwater goldfish to boil!
Neons (Tropical) fish and Goldfish cannot be kept together. Goldfish are cold water fish and Neons are warm water fish. Plus, to have 3 or 4 Goldfish, you would need about a 100 gallon tank, as they grow a lot. (18 inches).
