Dendrodoris nigra feeding

From: J. Kennedy

Found the Dendrodoris nigra in my aquarium, so cool. But was wondering what it eats. I'd like it to be able to survive in my tank.
Thanks for your help,

Dear JK,
When you say 'found' in your aquarium I guess that means it just appeared one day. If so, it has probably found something to eat in your aquarium. Can you give me some idea of its size? Species of Dendrodoris feed on sponges, D. nigra has been reported to feed on Halichondria dura Lindgren but most sponges are difficult to identify and difficult to keep in aquaria. If you are lucky you have a sponge which Dendrodoris eats and which can survive in you aquarium. If I were you I would just keep my fingers crossed that the sponge grows faster than Dendrodoris feeds.
Best wishes,
Bill Rudman.
