Yeah, a lot of people panic a bit when they start finding hitchhikers in their tanks - just remember, a lot of the things you may find are harmless (and some are pretty cool).

In this case, this appears to be a nudibranch - probably a sponge specialist. It doesn't pose a threat to your tank, and it'll probably starve.

I'll see if I can figure out a proper ID later when I've got more time, but, this little guy is nothing to worry about.

Not the reason for your tank crash either, thinking poor water quality and either your boxfish released toxin or brought sickness in

It has laid eggs

Any pics of the eggs?

My best guess for an ID at this point is an Atagema sp. - the closest I know at the moment are A. echinata and A. osseosa.

Nudabranch like note above. I had something similar many years ago - it was eating my large colt coral. So if you have soft corals keep an eye out for more.

Threw them away

So did a tank crash or is this a critter ID thread? I'm confused

OP had a tank crash if you read his other posts and thought this was the cause. Most people in the other threads think it was either poor water quality that lead to a stressed boxfish releasing its toxin or a sickness the boxfish brought in
