My ghost shrimp are dying off and I'm wondering if it's because of a snail boom. It's a five gallon tank originally shrimp only and two hitchhiker ramshorns have become dozens! Are the snails adding to the bio-load? Is there anything I can do? The ghost shrimp are from walmart and I've had them for three months. Theres who knows how many MTS in the gravel also. Thanks again for all the I've gotten since I've joined this site!
