Jep, assuming you are looking for some interest on the substrate (as opposed to fish eating leftovers), the Whiptail Catfish is a good fish. Check the info in the profile (click on the shaded name). Corys as Jackiebaby mentioned are certainly interesting. Oto catfish tend not to be on the substrate except when feeding from sinking foods, they spend their time on plant leaves, wood, even the tank walls, grazing algae. They need a group (as do corys). Loaches are interesting substrate fish, but they tend to need large tanks as most are 4-5 inches for smaller species and the others are much larger, and they need a group.
