Okay, so I'm going to be getting 3-4 banded kuhli loaches for my 10gal at some time in the near future (there will also be a mystery and a betta) and I'm wondering if you guys have any ideas for "toys" or things to entertain them (or entertain me). I'm going to have it planted but not very heavily, at least to start out, and want to get them something to play with, for lack of better phrasing. I'm intending on having hides, yes, but I did see that one person I follow on Tumblr has hamster tubes for his/her blue crayfish to run around in. Anyone have any ideas for similar? Would they be interested in tubes
