26g tank

[gavintc17]

I have a 26 g tank and I have 12 neon tetras, 5 true rummynose tetras, 2 small angelfish and 3 guppies one male two female. The tank looks empty and I want ideas for cool tank mates. I have a super strong filter. Any ideas?

Loaches or some sort of catfish on the bottom I think. Angelfish will be centre-piece fish so that looks sorted.
