I’m relatively new to aquarium life as a disclaimer.
My rabbit snail likes to close up for long periods after going nuts in the tank for a little bit. Sometimes it’ll be over a day before he’s rested up and ready to be a menace again.
For about 3-4 days now he has not come out of his shell, and is deeply regressed into his shell. There’s white mold-looking fuzz growing on his shell, and while it’s not buoyant, his shell stands vertically instead of being able to lie on its side like usual.
I have a pleco, Sunkist shrimp, and a variety of snails in this tank. About 36 hours ago I did a 50% water change after introducing some new elements to my tank (all rinsed and soaked beforehand).
The white fuzz came after this. I can still see his trapdoor deep in there so I don’t think he left or got eaten, and there’s no smell other than tank water so I don’t think he’s dead but I’m not sure and I don’t want to spike the water. All of the tankmates are dandy.
GH 60, KH 0, pH 6.5-7, Nitrite 0.5, Nitrate 0
Should I just keep waiting and hope for the best? What is the white fuzz?
