Weird Things In My Tank

This is one of the Scyphozoan Jellyfish in our pico-tank that we found clinging to the glass. They seem to like to attach to the glass on their backs and only move like jelly's when they move from one location to another. The pico-tank has become more of a science experiment than an aquarium, since we are trying to keep these guys alive out of shear curiosity of how big they will get.
