My loach basically hides all day and doesn't like to leave this rock area. I can tell he has eaten some because all the area behind the rock has been cleaned, but he looks very skinny to me. I have a small piece of driftwood I can add to the tank if that would help. I have tried blanched cucumber and shrimp pellets. I can try algae wafers, but he doesn't seem to move much. I will keep trying other stuff, but I am not sure if he looks good or not.
