I actually haven't seen anymore Harleys from my LFS (the better one at least.) and I think I have too many top-mid dwellers already (especially since the black neons love to school at the surface with the harleys.)
I'd personally ditch the serpaes and go with more harlies but maybe thats just me![]()
Y. Sidthimunki aka dwarf chain loach (jpappy has 'em) are cute, active buggers.
