So I put a clown pleco in on of my tanks to help with alge problem. He has been in the tank 3 days now doesn't seem to be eating much of the alge if any. He does a good job of keeping himself hidden during the day but I have caught him all over the tank at night. So my questions are is the alge in the tank enough to keep him feed? Do I need to be adding other food for him, I have alge discs and weekend feeders I could drop in but would really like to get rid.of the over growing amounts of alge. The tank is planted so I try to keep the lights on at least 9-10 he's a day so that of coarse is helping the alge grow.
