When I worked in the trade this was our most returned fish. We had one that despite our warnings to potential owners it was bought and returned at least 6 times. The last time to a customer who set up a tank just for the fish but returned it when he nearly lost a finger to it! It lived out it's days in a large tub at the back of the shop feasting on crabs and shop casualties.
lovely fish but not for the feint hearted
