I have one female guppy (I think it's a she), one Peppered Cory (1.5"), and also one large-ish bottom-side-up catfish (approx 4.5"). The bottom-side-up pet cat is generally well mannered, however not to be trusted around small fish. Lost a few little tetras to him. Cory is a hectic man, keeps to himself. The guppy ... well, it's a guppy.
If you're looking to re-home some, will trade for tetras. Various other south american types additionally taken into consideration.
