The Blue Flasher Wrasse (Paracheilinus cyaneus), also known as the Blue Flasher, is a stunning and vibrant marine fish species that is popular among reef aquarium enthusiasts. Here's a care guide for the Blue Flasher Wrasse:
1. Aquarium Size: Blue Flasher Wrasses are relatively small, reaching a size of around 2 to 3 inches in length. They can be kept in a tank with a minimum size of 30 gallons, but a larger tank is recommended to provide them with ample swimming space.
2. Water Parameters:
3. Tank Decor: Blue Flasher Wrasses prefer a well-aquascaped tank with plenty of live rock, caves, and hiding spots. They may seek refuge in the rockwork when they feel threatened.
4. Diet: Blue Flasher Wrasses are carnivorous and feed primarily on small invertebrates and zooplankton. Provide them with a varied diet that includes high-quality frozen foods like Mysis shrimp, brine shrimp, and other small meaty offerings.
5. Compatibility: Blue Flasher Wrasses are generally peaceful and can be kept with other peaceful reef fish and invertebrates. However, they can be territorial with other closely related wrasses, especially males of the same species or similar-looking species.
6. Male and Female Interaction: In a reef setting, it's common to keep a single male Blue Flasher Wrasse with multiple females, as males can be territorial and aggressive towards each other.
7. Water Flow and Lighting: These fish prefer tanks with moderate water flow and adequate lighting. They may appreciate some sheltered areas with lower water flow.
8. Disease Prevention: Quarantine new arrivals to prevent the introduction of diseases into your main tank. Regularly monitor their health and behavior.
9. Handling with Care: Be cautious when netting or handling Blue Flasher Wrasses, as they can be skittish and prone to jumping out of the tank if startled.
In summary, the Blue Flasher Wrasse is a beautiful and relatively small fish that can be a great addition to a reef aquarium. Ensure proper tank size, water parameters, diet, and tank decor to provide a healthy and vibrant habitat for these fish. Proper care and consideration of their compatibility and social dynamics will help ensure their well-being in your aquarium.
