eh better not get them then if they will feel uncomfortable. My LFS has a nano fish section and these are the available species:
pygmy Cory
Lampeye Killifish
various types of small Rasbora
various shrimps
White Clouds
Kuhli Loaches
honestly I am tempted to just get a group of Lampeye Killifish and try to breed them
maybe get some Pygmy Cory or shrimp as bottom feeders. It will be a planted tank !
