Check out Rubberlips, Queen Arabesques, Green Phantoms, Gold Nuggets(can be fragile), Bushy Noses, Leopard Frogs, Clowns, just to name a few. All plecos. Rubbers, Clowns and Bushys are fairly common and cheap. All others can be semi~rare and run $20-40. There's literally about 100+ different kinds of plecos, and many of those stay small. None listed above grow over 8"s, and most above only grow 4.
In fact, my Avatar is a Leopard Frog, and a good alternative to Zebras.
