I have a few mystery snails in my 29 gallon tank and out of those few one of them, a blue mystery snail starting acting weird today. This morning I found him upside down trying to turn himself back over at the bottom of my tank so I flipped him back over. Since that happened, he's been constantly climbing out of my water and just sitting there. I have a lid so he can't get out but I don't know if this is normal behavior for mystery snails. I know it' s not a female trying to lay eggs because I flipped the snail over and I know it's a male. All my other snails are acting completely normal and eating an algae wafer I just put in my tank. As of 2 days ago my water parameters were 0 ammonia, 0 nitrite, 2.5 nitrate, and 7.3 PH. I'm taking my water to be tested at my LFS again today. I have cuttelbone in my water for calcium and his shell looks normal too. I just did a water change in hopes to remove anything that could cause him to act like this. Is this health/normal behavior for a mystery snail? Thanks in advance
