Information on Hypselodoris bullocki

From: Santos Al Halper

I am A very enthusiastic reef keeper and I am very interested in The Bullocki Species (I have always thought it was Chromodoris but I guess that I was wrong about that) anyhow I am interested as to if anyone knows any particular species of sponge this nudibranch eats. I am very interested in keeping this species and would appreciate any info into this problem. :-)

Dear Santos,
Many popular books put this species in the genus Chromodoris. One advantage of the Forum is that it can you up to date with what the 'experts' are thinking about such things. One thing I am sure after looking at its anatomy is that it not a Chromodoris. It has features of both Hypselodoris and Risbecia and at present Hypselodoris seems the best place to put it, until a more extensive review can be done on it in all its colour forms.

As to what it feeds on, have a look at all the messages in the Forum on H. bullocki. It has been discussed at some length. There are no easy answer but at least you will get a feel for the problems. To find the messages, some a below your message on this page and some are on H. bullocki Page 1. another way to find stuff on H. bullocki is to use the SEARCH button at the top of each page, or in the yellow band at the top of each message.

Best wishes,
Bill Rudman.
