This is a very aggressive trigger, arguably the most aggressive. Its gets very larger, close to 2 feet, and will attack just about anything in the tank. Small ones don’t have all the color that the adults do. They should be kept in a large tank with large rocks as they will pick them up from time to time, and they should be kept with very aggressive tank mates, like other triggers and groupers. Small ones may not be that aggressive but as they grow (around 6 to 8 inches), they will become a major problem.
