Blue Dragon Nudibranch

Care Summary

The Blue Dragon Nudibranch is a spectacular pelagic species that feeds exclusively on Portuguese man-of-war and other siphonophores, which makes it essentially impossible to sustain long-term in captivity. It is not a reef animal in any practical sense and will not survive in a standard display tank because the food source simply cannot be replicated. This one belongs in the category of animals best left in the ocean, and we strongly advise against purchasing it for anything other than a temporary, specialized research setup. If you encounter one, admire the photos and move on, because no feeding regimen available to home hobbyists will keep it alive past a few days.
