Please meet Gary, my new aquarium snail :) I bought him to keep my aquarium with Ghost a little cleaner a little longer. He's pretty shy, but he did climb to the top of Ghost's "castle" during the middle of the night.
Oreo is totally jealous, of course....he would be jealous of a snail!
And, Ghost isn't sure what to make of him. He consistently 'stares him down' though. Last evening, he must have stared him down for a couple hours straight. It wasn't until I tapped on the tank that he finally broke out of his trance and swam around a little bit.
