This is Abraxos. I’ve had him/her (not confirmed) since early June (for ease I will refer to him as him).
He’s in a 4ft (120 gallons/450 litres) heavily planted tank. There are other Mystery Snails who are all ok. About 3 or so days ago, I noticed he was super withdrawn into his shell, so put him in his own container in the tank. Everything on him looks shrunken, and I’m not sure what’s going on.
There is a regular rotation of veg, algae wafers, snello for food. Temp is about 26C, PH around 7.6, nitrite & ammonia 0 (I need to retest for KH etc).
