I'm starting to think our golden mystery snail (Sherrif) has been injecting growth hormones. When my husband and I came back after the weekend holiday, we couldn't stop remarking on how much he's grown. I think we never noticed it until we were gone for a couple days. He's more than doubled!
His shell is more than two inches long and his body trails another half inch or so beyond that. He looks really healthy - he's always moving around the tank and his shell is *bright* solid yellow. Even his antennae are longer than they used to be! We've only had him for three weeks.
Is this a normal growth rate?
