Colored sea slug

January 7, 2001
From: Robin

I am trying to find information on the "colored sea slug". This is what my LFS calls it. It's body is black with raised yellows bumps on its body. They say that it is an algae eater only, but I would like to make sure. Can you help me with the scientific name and any information on it?

Dear Robin,
A question. What does LFS stand for? Is it aquarium trade jargon for 'live fish supplier' or something like that?

Now to identify your animal. I really need a few more clues. Does it look like Phyllidia madangensis? If so have a look at the other species in the Species List which are in the Family Phyllidiidae until you find a match or else take a photo and send it to me.

If it is a Phyllidia then I am afraid it is not an algae eater but a specialised sponge feeder. If could also cause problems in your tank by secreting nasty poisons into the water. But I can't really advise you until I see a drawing or a photo.

I am afraid aquarium fish sellers apparently are saying that nudibranchs are algal feeders so that you will buy them. All nudibranchs are carnivores, that is they eat animals, each species feeding on a very specialised diet which your aquarium shop will not have in stock. Have a look at the conversation I am having with Cody Mott at the moment on this very topic.
Best wishes,
Bill Rudman
