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.

Customer Testimonials

Michael B Lawton , OK
I really like the foxface lo because in my tank it is a very friendly fish. It has gotten along with all of the different species of fish that I have owned so far. Also, I am fascinated by its ability to change into what I call its "pajamas" at night or when the tank is dark. I would definitely recommend this species of fish for any amateur or professional aquarist.
Raphael T Douglassville , PA
This fish saved my tank which was being taken over by caulerpa. It has been the only species I've found that truly loves to eat this terrible algae.
Vincent S Foster City , CA
Great fish to have. They get more beautiful as they get larger, are peaceful, & easy to take care of. Also, change colors at night. Big fish leave alone as they are also venomous (rear spines). One of my favorite fish!
Chris K PA
An excellent fish, he is very peaceful and a beautiful specimen! Though he was extremely shy at first took him about 2 months for him to finally come out and swim with you right infront of the tank. Definitly a wonderful and awsome fish, worth the money and very hardy!
Han N Allen , TX
Its nick name should be Caulerpa algae Terminator. It helps to keep grape caulerpa under control in my reef tank.
Marcus R Danville , PA
This was my first time ordering saltwater fish of the Internet and while I was a little apprehensive Divers Den didn't fail me. The foxface arrived promptly and in excellent health. It had no difficulty in asserting itself and greedily competes for food with the resident bird wrasse and clarkii clownfish in my 300 gallon fowlr. He simply flashes those spines and the others give him a wide berth. Thanks for the great fish.
Kyle R Fort Worth , TX
My foxface lo arrived with brilliant color, even when in camo-mode. He likes to nibble at algae on rock, and definitely gets his fair share at the algae clip. He doesn't bother my tangs, and we really like how brilliant his color is.
