Concerning message #12545:

I had a question regarding A. fasciata. The ink they secrete, is it toxic to other organisms in an aquarium setting?

Dear Bill,

If you go to the General Topics List you will see there is a whole section of Sea Hare Topics including one on Ink Glands. Have look at it and the attached messages for some background information. You will see that they need to eat red algae to produce the purple ink. I suspect the ink is not toxic but it would be sensible to de-ink them before introducing them to an mixed aquarium by keeping them in isolation for a day or so and handling them a bit. If you then feed them on a green alga like Ulva [sea lettuce] they won't produce the ink. Some people feed sea hares with leaves of garden lettuce after quickly dipping it in boiling water. But anything you do is at your own risk.

Best wishes,
Bill Rudman
