I'd take it out!

 

[romeofoeve]

no, he is all green, almost neonish, lemme take a better pic.

 

[romeofoeve]

ive pinpointed it down to
Order: SACOGLOSSA
Superfamily: ELYSIOIDEA
Family: Elysiidae
its either Elysia gordanae, or Elysia flavomacula. does anyone know about seaslugs?

 

[maurice]

He resembles a sea hare some,but i am just not sure,i am searching a little to try and find out though.
