Right now I've got 4 yo-yo loaches that I think are at their adult size (4" maybe? I'm not really sure). I love these little guys, they're so much fun, and I would really like to get more. However, my LFS only has very little ones (probably about 1"? Again, I'm not sure.) Would my larger loaches bother the baby ones? If I do decide to get more loaches, should I wait until I find some larger ones?
