Hey, so I am really bad at numbers at I feel like I always overstock my tanks. Do you have like a ballpark guess as to how many of each I can put in?I can't recall if I had kuhli's in with mine or not. The puffers ignored other fish completely, though, so don't think they'd bother. Swap them for the cories, though, since both are bottom dwellers. I'm a fan of pencils more than tetras, so look at hockeystick pencils. Neat fish, get to be in the 2-3 range, happy in planted setups.
