sounds like they would be a good addition to my 10 gallon guppy tank. I don't mind if they don't reproduce in my tank, but I would definitely put a sponge over my filter intake. My ten and 29 gallon tanks are planted so anything that eats snail eggs gets my vote. Don't get me wrong I don't hate snails, just pest snails. It seems like no matter how well I clean the plants I get from one of my LFS I always end up with snails a few weeks later. I don't have room in my budget for anything new right now, but I will keep you in mind for my next addition to my tanks. Could you recommend anything from the cleaner crew varieties for my 29 Gallon Ram tank?
