Ok, guys, I need some serious help! I have a 50 gallon tank. My original plan was several fancy goldfish (4 or so while they are smaller, then back out to the ponds when they get a big larger), my female pearl gourami, and my sailfin pleco (only about 4 inches ATM, then out to the pond when she's larger if I don't have my 75+ gallon tank by then). But now, looking at my 20 long, I love the activity and have always wanted a large tank full of small fish and a couple large fish. What if I where to do the gourami, two-three goldfish (the largest is 4 inches, the rest are 1/2 that or less), the pleco, and like 4 billion (not really ) smaller schooling fish? I don't know what I want, though... Obviously, something fast enough not to eaten by my ever hungry goldfish, but something small enough not to add to the bioload much. Give my some ideas, guys! I have two ponds, so less goldfish is not an issue. I can play pond swap and tank swap and what-not. I want at least two, though, till they're larger anyway. Then they can be kicked out ;3 The tank will be heavily planted, and a 20 gallon sump is in the very near future.
