hey in my experience ive found the yoyo loaches to be huge pests to other fish in the tank there awsome fish tho. mine now swims around the tank like crazy, there big pigs too well mine is eats anything that touches the ground well and anything you put in the tank. i love kuli loaches there my favorite i want to get 1 or 2 more for my tank there amazing fish havent had any issues with them at all.
