I have a 5 gallon with a small goldfish in it that will be in the pond soon. I want glowlight tetras for it when I get rid of the goldfish. My question is, how many can I fit in a 5 gal? It has GREAT filtration... I might not clean it for 2 weeks nd there'll be zero ammonia... and the goldfish is 3 in. long and thriving. It also has a bio-wheel.
So how many can live in there?
