Sounds like shellies are in high demand and short supply locally.A few posters had asked me about buying my multies, I tired to respond but your mailboxes were full. I'm not selling any multies other than the couple of likely rogue males. It would be too disruptive and stressful to the brooding females and colony to break up the shell bed to catch them. You'd have to go through each shell (I have over 70 escargot shells in the shell bed) to figure out if there's a multi in them or not There's no other way in a 6 foot tank. Sorry.
