Suggestions for a small peaceful cave dweller
I found a bunch of terracotta hollow cylinders with holes at my LSF and thought it would be neat to put up two or three in my 57 tank, which currently only has plants but no hardscape. I would of course need something to live in it. Needs to be small and peaceful. Tankmates are:
25 cardinal tetras
2 big (!) pearl gouramis
1 female dwarf gourami
3 dwarf neon rainbows (leftovers from a previous school)
4 Trigonostigma hengeli (leftover from a previous school)
5 (?) otos
Because of the large number of fish I already have in the tank, it really needs to be something small. The only one I have come up with so far would be a peacock gudgeon. What other fish would work? Or maybe an invert?
