Hello. I have a 29gallon. With a 70 gallon filter on it. In the tank I have a gourami one molly. 3 Neon tetras and a 3inch royal pleco. I plan on getting 2 angel fish. The pet store said it was fine and they know there stuff. I kno all you say pet stores don't know anything but there is one guy that does. Is it too over crowed?? I might get rid of the neons because of the angels. Thanks !!
