Common name: yellow damselfish
General information
The Bicolor Damselfish, Stegastes planifrons, is a small and vibrant fish that is popular among reef aquarium enthusiasts. It is known for its striking two-tone coloration, with a front half that is a deep blue and a rear half that is a bright yellow or orange. This species is part of the Pomacentridae family, which includes other damselfish and clownfish.
Bicolor Damselfish are hardy and can be a good choice for beginners. However, they can become territorial and aggressive, especially in smaller tanks or when they mature. It's important to consider tank mates carefully and provide plenty of hiding spaces to minimize aggression.

Care
Stegastes planifrons requires a well-established aquarium with live rock for grazing and hiding. They are omnivorous and will accept a variety of foods, including frozen and flake foods, but should also be offered algae or vegetable-based foods to mimic their natural diet.
A larger tank is recommended to manage their territorial behavior, and they should be kept with other fish that can hold their own against a feisty damselfish.
Reproduction
Bicolor Damselfish are oviparous, laying eggs that are then fertilized by the male. The male guards the nest and aerates the eggs until they hatch. In the aquarium, breeding can occur if the environment is stable and there are adequate hiding places for the fry.
Habitat
Stegastes planifrons is found in the Western Atlantic, from Florida and the Bahamas to Brazil, including the Gulf of Mexico and the Caribbean Sea. They prefer shallow reefs and are often found in seagrass beds or near coral outcroppings.
