Orange Dragon Nudibranch - Bornella calcarata?
The Orange Dragon Slug (possibly Bornella calcarata) has a pale whitish body covered with a network of reddish-orange lines. The tips of the gill tassels are also reddish-orange.
The term "nudibranch" means "naked gill" and refers to the fringy, tassel-like gills visible on many species. This group include animals that we commonly refer to as "sea slugs" as well as the sea hares popular for algae control. As a group, there is not much known about many species of nudibranch and more are being discovered and reclassified continuously. While some like the sea hares are well studied and we know enough about their lif cycles and diets for them to be maintained, the diet and requirements of most nudibranchs is largely unknown. Most are thought to feed on sponges, polyps, tunicates. Some of the most colorful nudibranchs are actively collected and sold for aquariums but many more come as "hitchhikers" on rock and corals, for better or for worse.
Use caution when placing any nudibranch in your reef system if its diet is an unknown. Nudibranchs in aquariums are generally shortlived, both due to their natural short lifespans as well as the difficulty of meeting their dietary requirements.

orange dragon nudi
I bought two of these and when they arrived they seemed healty but they don't move much but when they do theyare allover the place BE CAREFUL AROUND PUMPS!! they lived for about two weeks and were gone. I never seen them eating anything so I cant say what they eat. I have several sponge tunicates etc no interest but awhile after they disappeared my system crashed bad . but remember the fish place did state they don't know what they eat so be careful!!! happy reefing. dave
