Here's what is in my community tank: 2 types of half beaks, von rios tetra, hummingbird tetra, 3some of guppies (recently added, courtesy of the coryologist as extras !), african 3 stripe glass cats, 2 huge SAEs, 1 figure 8 puffer, sids, flounder, sterbai and orange laser corys, sewellia lineolata, L104, L333, and L240 plecos (3, 6 and 1 in numbers), reg glass cats. I think that covers it. Quite a mix, but they all co-exist quite nicely, even had a spawn from the sewellia lineolatas. Except for the guppies, they have all been together in the tank for over 2 years. Good luck.
