Size of Hexabranchus

June 22, 2002
From: Valeria Safonova

Dear Bill,
Lately I was given a few sea slugs as a birthday present. It's quite a new animal for me and now I try to understand what to do with them. Thanks for the information of their feeding that I found on your site and the List of Food Habits, this weekend we will try to “fish” the right food for them (we are living on Comoros Islands). Amid them there is a very beautiful red species, which we call Spanish dancer and which resembles Hexabranchus sanguineus. I've read that it can grow till 50 cm. The question is if it is always the case that the adult is so enormous or it depends on something? At the moment it is 6 cm and I do not think that it will be possible to keep it in the aquarium if it becomes so big.
Thank you in advance,
Valeria

Dear Valeria,
What a beautiful place to live. I guess it is also a good place to see if you can keep nudibranchs alive in your aquarium because you can always put them back in the sea if things don't work out. I am not sure how long it takes Hexabranchus to grow so big, but if you are fortunate to get the right sponge for your 6 cm animal I am sure it will live in your tank for some time before you have a space crisis.

If you have photos or observations on sea slugs from the Comoros they would be very welcome.
Best wishes,
Bill Rudman
