What is the best food for Hermissenda?

July 20, 1999
From: Benjamin Ross

I am a summer student working with Hermissenda and a few animals died in the aquarium after 2 weeks. Currently I am feeding them with Cichlid Gold by Hikari. Is there an alternate food which would be better for them? Also, I am curious as to their natural food source.

Thanks.

Dear Ben,
Hopefully someone with personal experience of this animal will respond to your question. Hermissenda crassicornis is a generalist feeder. It feeds on hydroids, such as Obelia and Tubularia, as you would expect for an aeolid, but has also been reported to feed on small crustacea, other nudibranchs, sea pens, ascidians and stranded jellyfish! Harrigan & Alkon (1978) raised specimens in the laboratory on the ascidian Ciona intestinalis, mantle muscles of the squid Loligo and the mussel Mytilus. Perhaps chopped up pieces of marine invertebrate tissue are worth a try.

Reference:
• Harrigan, J.F. & Alkon, D.L. (1978). Larval rearing, metamorphosis, growth and reproduction of the aeolid nudibranch Hermissenda crassicornis (Eschscholtz, 1831). Biological Bulletin, 154: 430-439.

If you could let us know what research you are doing with Hermissenda, perhaps someone visiting the Forum could give you some advice.

Bill Rudman.
