Will a higher temperature in a nano reef cause snails to instantly die? I put two astrea snails in my tank after checking all h20 parameters-all perfect- and then realized the temperature was at 90 degrees. I live in TN- it's been almost 100 here for the past month- and it's hard to keep the temperature steady in this tank. My hermit crabs are fine- thankfully there are no fish in this tank. I moved the tank to another room where the temperature is cooler and now I have it at a steady 82. Could this have been it? I want to get more snails, but they are $2 a pop, and plus, I don't enjoy murdering the little bastards. So, what do you think?
