Blue Line Trigger (Indian Ocean) Groupers tangs naturally graze on algae

tangs naturally graze on algae throughout the day

while females are warm earthy shades with white bellies and a dark spot on each scale

which will surely damage the colony

and a single horn extends from its forehead reaching at its longest to the mouth

Demosponges such as this are comprised of silica spicules which may be extremely irritating if touched

Blue Line Trigger (Indian Ocean) Groupers tangs naturally graze on algaeTriggerfish are extremely personable and entertaining, and make great tank mates with other fish of similar size or temperament. They will eat invertebrates, especially shrimp, but also other crustaceans, mollusks, bivalves, sponges, tunicates, feather dusters and more. They may move and flip over rocks to search for food underneath. They do not typically bother corals. They may chase and bully other fish, especially those smaller than themselves.
