Had my sister inlaw grab me a few turbo snails to help mow down some of my hair algea. Looks like petco sold her Red Collar Snails / red foot moon snail / Norrisia norrisi instead as well as some top crown snails,astrea undoza. I believe they are both coldwater species? I run my tank at 77. Am I going to have a bunch of dead snails on my hands here pretty soon?
