Would some kind soul take a look at the photos I have on this page
http://goatdairying.com/fish/marine/marineunknown.html and tell me what they are. I've searched everywhere and can't find them. This is a very new setup. The guy at the shop I bought the live rock thinks the white one might be a mantis shrimp. Big thanks miskairal |

The first is some kind of nudibranch.
The second could very well be the mantle of a clam that is deep within the rockwork.

Hi Miskairal,
As Marc and Wayne said, the white one is a nudibranch. It's probably of the Aeolid type although it could be a Dendronotid or even an Arminacid. Here are a couple of sites that may help with a more exact I.D.: http://slugsite.tierranet.com/ - This is run by a guy in California, I believe, but it has numerous links to sites for Australian and Australasian nudis. http://www.seaslugforum.net/welcome.cfm - This site is run by Bill Rudman of the Australian Museum and is searchable. If you can't find your nudi then you can send the picture to them and Bill will probably be able to I.D. it for you. FWIW: If I guessed right about the group your nudi probably feeds on cnidarians but may be a total specialist on a particular species. In any case, keep an eye on your corals, anemones, and hydroids to make sure they aren't being damaged too much. In the wild, these things almost never kill their prey - they usually just bite off a tentacle or two and move on. Things could be quite different in an aquarium though. OTOH: Nudibranchs are generally considered to be hard to keep since their diets are usually very specialized which leads to them starving more often than not. Sluggishly yours, Alex |

Sluggishly yours, Alex Thanks Alex, I've been to both sites and I couldn't find my exact "nudibranch" so asked but that was 6 days ago and I've not found a reply in the forum :( Mine does look like it's from the Aeolid type. Yesterday I discovered a new, smaller one of these things. Only about 1/2 cm long. |
