What to add to my tank? any suggestions?

[Don90]

As above, my tank looks a little empty and I feel like getting some "uncommon" or "rare" fishes in my tank. Any suggestions?

My 2ft tank

fishes: 1 red lizard catfish, 2 zebra otos, 6 cardinal tetras(2 platinum cardinals included) and 1 oto.

I have an ap.sp mamore red male inside the tank temporarily so the female in the other tank can mature peacefully.

SOOooOOOoo, any suggestions?
