Cat Nudibranch?
(Vayssierea felis?)​

I received some new frags today and during the coral dip I noticed a tiny red spot on an acropora frag. I was really worried to have found an Acropora Red Bug (Tegastes acroporanus) or Red Planaria (Convolutriloba retrogemma), but apparently it's a little sea slug.

I assume it is a Cat Nudibranch (Vayssierea felis) which eats Spirorbis (see post #81), and Salmacina tubeworms. The only thing that is a little bit odd is that I can only see one Rinophore (olfactorive organ)... Maybe I am completely missing something or it's just an oddity of this specific slug like a birth defect or an injury.

@ISpeakForTheSeas, there you have it. You said you liked being tagged, now you have to deal with the consequences

I'm currently trying to offer it some spirorbid worms, but it's not touching them besides showing some short-lived interest when pushing one towards it. Maybe the coral dip is still causing it some problems or it doesn't match its specific diet.
