Todd Gardner (known for his fish breeding skills) shared this image and video with me. It settled out of the plankton in his larval system, and in a week's time it had tripled in size....and he discovered this little nudibranch that has been consuming his hydroid population. A pest eater, how cool is that? Hope to get a better identification of this little guy soon. This tiny beast is 8mm in size.
