Balistapus Vetula-Queen
This is a very aggressive trigger, arguable the most aggressive. Its gets very larger, close to 2', and will attack just about anything in the tank. Small ones don't have all the color as the adult do. Should be kept in a large tank with large rocks as it will pick them up from time to time. Should be kept with very aggressive tank mates, like other triggers and groupers. Small ones mayn't be that aggressive but as it grows, to say 6"-8", it will become a major problem.
