i added prazi pro to my system about 3 days ago (yes i did my research before doing so, and i've actually used it in my main tank once before with no ill effects) and about the same time i noticed my clam was no longer opening and that my snails were hanging around it's foot. i've had it for months and it was doing great, all my water parameters are in check. also is there any chance of feeding it? the mantle is still there but not coming out, and i checked the foot yesterday and it was already deteriorating and there was a hole, any chance of it recovering if i put it in a different tank?. thanks for any help!
