is one of the best places to research basic fish info.
leporinus fasciatus is a beautiful fish, but a fast grower, and will grow 10-12" long. They're also aggressive, especially to smaller fish. IDK if they'll eat plants or not, but I think it's a distinct possibility. At any rate, it's not a species I'd recommend for a community tank.
There's many species of whiptail and banjo cats, and the adult size can vary pretty greatly depending on the species. In general they're peaceful, fairly quiet fish. Banjo cats I've kept several times, and they spend most of the day hiding so you won't see them often.
Otos are great planted tank residents. Only worry is to be sure that nothing else in the tank is big enough that it might decide to eat one. They've got sharp spines in their pectoral fins that they can lock in place as defensive weapons, so would-be-predators often end up seriously wounded if not dead along with the little catfish.
Von rio tetras get fairly large for tetras and need to be kept in decent-sized schools, so need a large tank (55+ gal) I haven't kept them but I've heard some reports that they can be nippy with long-finned fish.
Botia dario (Queen loach) is a loach that gets about 6" and needs to be kept with others of its own kind, so also needs a 55+gal tank.
Honey gourami is a good planted tank fish and usually a good community fish. They only get 2-3" so can be kept in tanks as small as a 10gal (though personally I'd recommend a 15gal). You do need to be careful when trying to keep males together in the same tank as they may become aggressive towards each other and need to be separated. Most of the fish you find in the pet stores will be males, as females are much less colorful.
