Phyllidia coelestis from Indonesia

I found a pair of Phyllidia varicosa and was wondering if they are juveniles?

I took the photo on Starship Reef in Wakatobi marine park in Indonesia on March 29, 2004.

Best regards,

Dear Ulrike,
This is Phyllidia coelestis. One immediate difference from Phyllidia varicosa is the median black band on the mantle.Without some indication of size from you I have no idea whether these are juveniles or not
Best wishes
