I just recently realized taht one of my panda cories lost its barbels...or at least half on one side and most on the other side. It doesn't seem to be as active as the other panda cory I have, and doesn't seem to be able to find any food. Whenever I see it being active, it's always eating algae off of the side of the tank even though I've dropped spirulina pellets and Hikari sinking wafers. So I was wondering if its lack of diet...or lack of ability to find food has anything to do with the injured barbels, and if they'll grow back. Thanks
