The rabbit's long ears, which can be more than 10 cm (4 in) long, are probably an adaptation for detecting predators. They have large, powerful hind legs. The two front paws have 5 toes, the extra called the dewclaw.
However, Moorish idol larvae spend a long time drifting through the open ocean before they mature, so regional populations donât remain isolated enough to develop particular traits. Because of its beauty and its identity as a quintessential reef fish, the Moorish idol is a very popular fish in the aquarium trade.
The Moorish Idol is a very finicky eater and to make matters worse, their protruding mouths are sometimes damaged during collection and transport. Another good reason to use the quarantine tank when you first get them is to get them eating without any competition.
