Yesterday I received my order for some Astera snails. Once I added the snails to the tank (7) all but two immediately took off. The other two were moving slower than the rest but I figured they would be fine by morning. After about 30 minuets of watching to make sure everyone was okay I turned the lights off and laid down in bed. Probably an hour or two later I got up and shined the red light in the tank to check on everyone and that dang emerald crab of mine had his GRUBBY CLAWS pulling out the innards of one of my new snails! I was considerate enough to let him finish so the poor snail at least didn't go to waste and then removed what was left over to clean the shell. I feed my emeralds and hermits sinking pellets every other day as we have not added fish yet and want to prevent any aggression between them and the snails for food. What would you do with said emerald? Sump? Leave him be? My other two have not displayed any sort of aggression and honestly this is killing me because they are so entertaining to watch. This morning I could only find 5/6 snails left in the tank and wondering if he got another one too.
