Maroon Clownfish
Premnas biaculeatus
Water Parameters
About
The Maroon Clownfish is the largest of all clownfish, with females reaching up to 15 cm. Its dark reddish-brown body with three white or yellow stripes (in the Gold Stripe variety) is imposing. It has cheek spines (preopercular) that can cause scratches, justifying the name Spine-cheek Anemonefish.
Behavior & Temperament
The largest and most aggressive of the clownfish. Dominant females can be extremely territorial and may even bite the keeper’s hand. They form stable pairs with their host anemone.
Feeding
Omnivore. Accepts marine flakes, pellets, mysis, brine shrimp, chopped shrimp and frozen foods. Voracious appetite, accepts practically any food.
Breeding
Oviparous with parental care. Lays eggs near the anemone. The male tends and cleans the eggs. Breeding possible in an aquarium with an established pair.
Care Notes
Aquarium with a host anemone (Entacmaea quadricolor is preferred). Watch out for the stinging tentacles when handling. Females can be very aggressive – introduce the pair simultaneously. Provide adequate space around the anemone.
Compatibility
Aggressive toward other clownfish and fish invading its territory. May intimidate smaller fish. Keep only as a pair. Compatible with large, robust fish that do not compete for the same space.
