Best tankmates for Syncrossus hymenophysa?

[Alaskancorydoras]

I have 5, under 2", in a 55 gal. I am wondering about good tankmates for them, as I have no other GRRR fish. Ideally I'd like all levels of the tank occupied, and can always get more Tigers if the bottom level is under-occupied. I also have a line on inexpensive red-finned blue loaches, if they would play nice together.

You can house suitable tank-mate fish of a medium size like the members of the Puntius and Danionins genus.
