The Blue Eye Bristletooth Tang is an exceptionally functional and attractive surgeonfish featuring a subtle, dusky reddish-brown body covered in fine dots and stripes, offset by an electric-blue ring around the eye. As a member of the Ctenochaetus genus, this species possesses specialized comb-like teeth designed to scrape film algae, detritus, and micro-algae directly from live rock surfaces and glass walls. They are constantly active, making them fantastic maintenance fish for keeping marine aquariums clean. They are peaceful toward most community fish, though they may defend their grazing territory against similar tangs.
