Sea Slugs as Pets?

August 10, 1998
From: Sam Noe

I am 6 1/2 years old and I love sea slugs. I have petted them at the Long Beach Aquarium. I have a book of many beautiful sea slugs. I would like to be able to keep one in an aquarium. Do you think that it's possible? My mom is not so sure.

Thank you for helping me.

Dear Sam,
Keeping any sea animals in a salt water aquarium is not easy because you have to be sure that the amount of "salt" in the water stays constant. You would be best to get advice from an aquarium shop, or look up some books on how to look after a saltwater aquarium.

If you are interested in Sea Hares, which feed on sea weeds, they are probably not so difficult because you can probably feed them on lettuce. Have a look at the messages about Sea Hares .

Nudibranch Sea slugs however, are quite difficult to look after, because they are very fussy feeders, eating only one or two types of food. Their food is usually sponges, hydroids, sea anemones etc, and other colonial animals which are even more difficult than nudibranchs to keep alive in aquaria. It is possible to keep some nudibranchs alive in aquaria for some weeks without feeding them.. but what you are doing then is starving them.

If you are near the sea and would like to keep a few for a day to two to see what they do, then it is quite easy to keep them in fresh sea water without feeding them. But after a day or so you should put them back carefully where you found them. To keep them for a longer time is quite difficult.

Unfortunately our computer cut off your email address. Could you let me know what it is please so I can add it to your message .. Bill Rudman.
