Went on a 2 Week Vacation to Ponce, and I come back only to see a huge amount of snails, everywhere. My setup is a 40G breeder with a P. Polli if it matters. I need some sort of permanent solution. I used to just keep them in check by taking them out of the tank whenever I saw them and destroying them with a sledgehammer (really yeah), but that is useless with the massive population now! Help!
