Does anybody of you have an experience with keeping this fish? I have 240 gallons tank with 5 tangs. I've heard that those fish can kill my large cleaning shrimps. Is it true? There are different information about their maximum size. What about feeding? Is it possible to accomodate them to dry flakes? How often i will need to feed? And finally how many males and females i can keep in my tank? I have large space for swim and not powerfull light (only about 600W - mainly soft corals) what can be suitable for fish and their colours.
