Rate: (24 Ratings)
One of the most beautiful and most sought-after marine reef fish is the Bicolor Dottyback, also known as the Bicolor Pseudochromis. They are amongst the hardiest fish available and are very easy to maintain if given the proper aquarium environment. They originate in the Western Pacific ocean, but are also captive bred to make them more readily available.
The Bicolor Dottyback can be an elusive creature, preferring to hide in the cracks and crevices of their aquarium. Despite their small size (approximately 1"-2" when full grown) these fish can be extremely aggressive toward other fish and more mild mannered species, especially in the restricted confines of a small tank. Great care should be taken to ensure that the Bicolor Dottyback is in a stable environment, preferably the only one of its kind in any given aquarium.
The appearance of the Bicolor Dottyback is particularly intriguing, as the back half of this fish is orange-yellow, while the front half is a brilliant violet color. These fish are approximately 1"-2" when fully grown. Their slender and sleek build make it easy for the Bicolor Dottyback to dart in and out of cracks and crevices within the reef.
As all dottyback species, Bicolor Dottyback are mostly carnivorous. They prefer meaty foods such as mysis shrimp, brine shrimp, finely chopped seafoods, small crustaceans and zooplankton. When you're not supplementing their diet, Bicolor Dottyback will spend time hunting for live food amongst the rocks and corals, and will feed on bristleworms as well. Among dottybacks, sessile invertebrates are not at risk.
When good tank keeping practices are followed and ample nutrients and food are regularly provided, Bicolor Dottyback can easily live several years in a marine aquarium environment. They are healthiest when kept in low lighting with adequate tank filtration.
All dottybacks are hermaphrodites. Since each fish can adopt either male or female sexual organs, adding two like species in a tank together will result in a pair. Spawning Bicolor Dottyback in home aquariums has become quite frequent, although those with an interest in raising them should do further research before attempting to raise the fry. Bicolor Dottyback are hardy fish are relatively easy to keep in captivity, and can successfully raise young in an aquarium under the proper conditions.
