I've got Glowlight Danio's & Neon Yellow Rasbora with mine and they are fine. I think you will be safe with most small non predetory fish with small mouths, like Neons, Halequins, small barbs like pentanzona, etc.
I would't trust any Cichlid's with them as my cosins tried them with Agazizzi Dwarfs & also Kribensis, but they eat the smaller ones after lights out.
Have lots of moss & plants to give them the best chance.
