Discodoris atromaculata feeding

June 7, 2007
From: Anne Kloeppel

Hello,
I`m cultivating sponges for my PhD including some sponges of the species Petrosia ficiformis, which Discodoris atromaculata lives on. When I collected the sponges [Croatia, Northern Adriatic Sea] I didn`t see any Discodoris. Back in the aquarium however one ate all the sponges so nothing is left over. It has got really huge over time but I think it is is hungry now. Is there a possibility to feed it in an aquarium? Does it just feed on Petrosia ficiformis?
Thanks for your answer!
Greetings
Anne

Dear Anne,

I am afraid you message was caught up in the large backlog so it may be a bit late for the Discodoris. As we study sponge-feeding dorids in more detail we are finding that many have very specific diets. There is a list of references on the Forum to research on the biology of Discodoris atromaculata. I think you will find that it only feeds on Petrosia ficiformis. In your studies it would be interesting to know what other dorid nudibranch you find feeding on particular sponges

Best wishes,
Bill Rudman
