I have no experience with them, but PlanetCatfish says yes.

They are quite sociable as big cats go and it is possible to keep a group of these catfish in one tank. Three Lima shovelnoses would do well as a group in a large enough tank. This is especially true if all three are raised in the same tank together. Other tankmates must be chosen with great care. Large cichlids could be experimented with, but should not be aggressive species. Large plecos and other catfishes would be great tank-mates.
