I got two when they were about two inches long they and are both over 5 inches in a year or so. They eat everything flake, frozen, nori etc... feed them heavy and they grow fast and they are model citizens never had an issue with either one. They do change color a lot so don't be alarmed if they go pale
Yes, they change color a lot and the two I had spooked very easy.
Rabbit Fish like algae. This is what live aquaria says:
The Foxface Lo, also known as the Foxface Rabbitfish, has a very unique body color. It has a mottled yellow-brown body with a dark chest. The face is very light in color and speckled on the lower half. They are a very hardy fish, and are great additions to the newly-established tank.
It may reside in a 125 gallon or larger aquarium. It is a very peaceful species except when housed with other rabbitfish. The Foxface Lo may be housed with more aggressive fish. Its predators will tend to leave it alone because of its venomous dorsal spines. Rabbitfish are generally reef-safe if they are well fed. If not, it is possible for them to nip at and consume some species of LPS and soft corals.
The Foxface Lo diet consists of a variety of fresh vegetables and undesirable species of algae. It does nip and possibly eat some soft and hard coral polyps.
I have one and he’s a total chill little guy. Very nice and gets along with his tank mates but will not hesitate to defend himself and stick out his spines if he gets the occasional nibble from someone else.
The one I have is completely chill. He loves pellet food, nori, and any macro algae he can fit in his mouth. He's kind of shy, but always comes out during feeding time. Some of them will not eat nori in big sheets on clips. If yours doesn't, just tear it into small pieces and submerge them.
