Hello, I'd like to add a snail to my 30 gallon tank GBR tank. I keep it at 84 degrees so it would have to be ok with those temps. I would prefer it not lay eggs or reproduce and have a taste for diatoms. I had a BN pleco but it died, I've never kept snails so I'd like to try. I read Nerites would be good but even a single female can lay eggs and I don't want that. Thoughts? Thanks!
