Maroon Clownfish

The gold-striped maroon clownfish, or premnas biaculeatus, is
one of the most common varieties seen in saltwater home
aquariums. It’s also one of the largest, growing to as much as
six inches in length.

While young, the fish are the same maroon/red in the body, but
their three vertical body stripes start out white, and gradually
take on a yellow hue, turning gold around the time of maturity
at one year of age.

Like other clownfish, they have a sexual dominance pattern,
where they all start out as males, but in a pair of maroon
clownfish, the more aggressive fish will develop into a female
of larger size. In groups, there will be one large, dominant
female, one smaller breeding male, and the rest will remain
males that are even smaller, and not sexually active.

These are among the easiest of clownfish to breed, and are quite
hardy, making them suitable for the new aquarium enthusiast.
However, they are also the most aggressive of clownfish, and if
you have other varieties in the tank, you can have territorial
disputes.

They enjoy an aquarium kept at 72-78F, a pH of 8.1-8.4 and a
diet of meaty foods.
