Rectangular Trigger

The Rectangular Trigger, Rhinecanthus rectangulus, also known as the Rectangulus Trigger, features a distinct body shape and a thick dorsal spine. It has a beautiful cream-colored face with a brown and black band across their body and a black triangle on their tail fin. The Rectangular Trigger will use its unique body shape to wedge itself into crevasses in the rock for protection. Their rough scales make them difficult to handle in nets so use caution while netting.  As an active fish, it will spend most of its time searching for food, including small inverts, so tank mates should be chose carefully and they should not be housed in a reef setup. Growing up to 12 inches they require a tank of at least 120 gallons with lots of filtration to keep up with their meaty diet and high waste load. Feed them 1-2 times a day a diet of clams, shrimp, krill, and squid to help keep their teeth trimmed.
