I have a 10G feeder tank stocked with goldfish. The first 2 weeks after getting a dozen new fish the alge buildup is going on strong. Decided to get an alge eater instead of scrubbing and filtering the stuff, so i got a golden mystery snail. He has done well the first 2 days but i'm wondering if the alge in the tank will be enough to keep him happy or will i need to get him alge wafers? He is about 1" across.
