This sea hare, turns out is a "dwarf freckled sea hare."
It never ceases to amaze me how small these organisms can be.
I've seen the regular sized sea hares that can be purchased at pet world that are as big as my fist, but this guy is as small as the first knuckle of my thumb.
I watched him crawl around for half an hour for a moment of truth or catastrophe, and the first conflict was when it slithered up to one of my hermit crabs and kept trying to crawl over it to clean its shell.
The hermit pushed it, stepped on it, pinched it, you name it, but it finally got on its shell without inking and cleaned that shell to a fine polish.
Whatever catastrophes may come is going to really have something else to measure up to.
As usual, John @ RC nearly doubled every multiple item i ordered. I am going to have inverts over every nook and cranny each time I look into that tank for quite a while.
