Typically 2” to 4”, may reach up to 15”.

Generally reef safe, but, they may bury any corals near the bottom of the tank in heaps of sand. large specimens may eat small inverts. Sociable. Best kept in pairs or groups of it’s own kind. Gets on well with other reef fish.

SIZE WARNING! THIS FISH CAN GROW EXTREMELY LARGE, AND MAY DO SO VERY QUICKLY!

All fish with a large potential size may need special care, and may require a tank set up in a particular way to suit their specific needs. Large fish need a lot of space, even as juveniles they may need large tanks to get enough exercise to develop properly. Large fish may view smaller tankmates as food. Large fish may sometimes damage equipment and bite through power cables. Also bear in mind that large fish can eat a lot of food. It’s not unusual for 1 large fish to eat several packs of frozen food a day, which can be expensive. Large fish can be difficult to rehome, so do not purchase them unless you already have the facilities to house them at a larger size.
