i dont know what the problem is with chinese algae eaters,i bought 2 from the fish shop named golden and common sucking loach and 2 small ones names chinese algae eaters.i thought they were different species but reading what people have wrote, they just seem to be different aged of the same fish.either way i have had no problems what so ever,they just hang at the bottom mostly sucking away at stuff on glass, caves,plant.
here is a picture off google what my common sucking loach looks like:
