i got exactly 1 pest "bladder type" pest snail in my new nano tank, some how either transferring stuff from another tank, or in with the couple plants I bought, but I just counted 8 clutches of eggs, on the drift wood, and glass... they blueberry snails are live bearers, so they must be from the one pest snail I saw the other day... I guess I need to keep a tweezers here, and waste no time removing any I see... I'm going to take a wet papertowl and wiped the few on the glass and do my best to remove the blobs from the wood...
