I'd like to make a tetra tank and I just wanted to know what would be best for my tank and which tetra species are compatible. My tank is 29gl and is taller then long. Some of the species I'd really like to have are long fin serpaes, pristellas, beuno aries, glowlights, black neons and black skirt tetras. Are all these guys ok? And heres a catch, I already have a wag tail platy and two juvenile mollies, the platy I could part with if I had to, but the two mollies were born in my tank and they survived a major power outage that lasted five days in the middle of Dec. in 50-60 degree water, when all my other mollies, rasboras, and gold tetras died, so I'm kinda fond of them.
