I have my Bahia Red in with an oscar, sev, ornate bichir, clown loaches, plecos, and a flagtail.
I also have some Gymno. labiatus and Geo. abalios (which I'm about to split up so I can cool down the Gymnos and start conditioning them for future breeding) which are currently with tetras, a flagtail, and a uaru. I also plan on adding some cories and maybe something else once the abalios are in their own tank
