Just wondering if this is normal. . I have a Nassarius snail, have had him since I started the tank. (early January of this year) Have gone through several Trochus snails already. . Water changes are regular, and don't overfeed. (tank has been fishless since February, due to clown passing away from ich) I caught the Nassarius snail latched onto the new Trochus snail, separated him several times, but he always went back. Needless to say, that new Trochus is no more. .he's not moving. I'm guessing I'm going to have to get rid of the Nassarius snail and just get Trochus snails, that I can't have both? Has anyone else ever had this happen?
