What is this?
 

I found this in my tank this morning. It's about 1" long (max).

What is it? It looks like some kind of slug. Looks kinda cool with the colours.
Is it reef safe? I don't have any corals yet, but would like to in the next month. Tank has been running for about 2 months and has 3 fish in it.

Minatus Grouper
Magnificent Foxface Rabbit Fish
Maroon Clown

110g with 120 lbs live sand, 70lbs live rock (more coming) as well as some other "dead corals" that are starting to grow algae on them.

Mg is a little low as is Calcium (Mg 1230ppm Ca 400ppm dosing to raise)
Kh 8
Phospates 0
Nitrates 0
Ph 8.25

Thanks

Wow pretty, so pretty in fact that I would imagine its not reef safe. Looks like some kind of sea slug to me. Try posting your photo at http://www.seaslugforum.net/ there are lots of nudibranch enthusiasts there that might be able to help you out :biggrin:

That is one cool animal, I like it I would take it off your hands if I were closer and youo didn't want it. It would be interesting too study..
