#742: Tang

Tang are various species of Acanthuridae fish, related closely to Unicornfish and Surgeonfish. This particular species, the Blue Tang, is widespread throughout the Indo-Pacific, but not common anywhere. She is very popular in the aquarium industry, despite following a fairly delicate diet and being prone to parasitic infections. She feeds on algae and plankton. When she is ready to breed, her colour lightens to a pale blue. Males will court her aggressively, rushing to release their sperm into the water with her eggs. These float upwards, attached to a bubble of bouyant oil. These will hatch in a day into tiny transparent larvae.

If she looks familiar, that's because she's Dory from "Finding Nemo". Look, I found her!
