Weird nudibranch

[Quinn]

Yet another nudibranch, this one much larger than all the previous ones I've found in my tank. Probably 2" long fully extended. Tan/yellow-green body, greener on tips of "branches", tiny blue spots all over.

Any ideas on whether he should stay in the tank, the fuge, or come out altogether?

No advice but it's sure creepy looking :evil:

He's a monster among nudibranchs. I tried poking around on seaslugforum.net but the only listing is by species, not location, colouring, size, etc. As he is green, I am assuming he eats algae, therefore I am tempted to put him back. He's a similar colour to the sea hares we see in local shops here, but of course the body shape is very different.

Success! I am nearly positive he is the species described at http://www.seaslugforum.net/stylstri.htm, a sea hare, not a nudibranch. Consumer of algae, and therefore he is back in the tank.
