Thanks for your response regarding my nudibranch's dietary requirements. Since the pet store told us it would eat algae, we weren't aware of its dietary requirements until we got home and started reading. There should definitely be a law against collecting such sensitive species!

Anyhow, the sea slug is in our tank, so we will do our best to keep it alive. It's definitely beautiful. From your additional info, I believe we have Hypselodoris bullocki, the pink color phase. It seemed that the best info you had suggested feeding Dysidea or Aplysilla sponges -- we'll try to acquire those. If you have any further info, we (and our sea slug) would certainly appreciate it.

Thanks again.

Laura and Larry

Dear Laura & Larry,
Glad to be of help, from Steve Long's message and yours, it seems that many pet shops are saying they eat algae. I'm afraid I haven't anything to add to what I've said earlier. Live sponges are a bit of a risk in aquaria unless you are sure of their identification as some release nasty chemicals into the water and all of them mess up the water when they actually die. Certainly if you can identify locate a local species related to Dysidea or Aplysilla it would be worth trying a bit but sponge experts are a bit thin on the ground I'm afraid. With luck you might someone knowledgeable in your local museum or university.

Best wishes,
Bill Rudman.
