Nudibranch?!

Idaho Mojo · Apr 16, 2018

Found this guy crawling on some rock a bit ago. Is it safe to leave in my tank? Or put it in the sump?
My DT has Gsp, zoas, daisies, hammers, and mushies for coral, some gobys and a damsel for fish, and turbos, blue legs, nasarius, and conch for clean up.
Sump has emerald crab and hermits.

Oh awesome! Its only about 1/4 inch long. Do they get very big?

No they stay pretty small.

Hey! I found 3 more that are considerably smaller, but seem to be more of an orange/yellow color. Do you think they are the same species?
I'm starting to think I may have had some nudi eggs on some coral I bought...[emoji29]

They are most likely the same if they look like the one you posted just different colors. They come in different colors.
