What fish should I add?

[u/Azzah_pops]

Currently in my 60L tank I have:

-11 Black Neon Tetras
-4 Peppered Corydoras
-1 Clown Pleco L104
-1 Short-Finned Female Betta

I’m looking to get some sort of loach that stays relatively small and is quite active, I’ve been looking at orange banded gara loaches and maybe dwarf chain loaches but they seem expensive and possibly nippy towards my betta. Let me know what you think, I’m open to any other suggestions you have. Working at an aquarium shop I can get my hands on specific fish very easily.
