ok so i have 6 corys, and 4 bolivian rams. the tank is done cycling, and i have 2 filters, aqua a/c 20, and a cascade. i have some hornwort, a bubble wall, and 2 snails. do have room for 1 betta with the big graceful lookin fins? are the betta even compatible with the bolivian rams? oh and btw, what is a good diet for my bolivian rams? i want them to look as healthy and colorful as possible, although they're kinda brownish right now cuz i just bought them yesterday at the lfs.
