I have a 33 US Gallon tank. In it I have two large fancies (approx 4"), one baby pearlscale (1"), one yellow goldfish (2"), and two weatherloaches (6"). Do you think I have overcrowded it? Starting to regret getting the yellow goldfish now, was a bit of an impulse buy. I don't mind getting a bigger tank in a few years for them if need be. Do you think I should take the goldfish back?
