Halichoeres cyanocephalus is also known as a Yellowcheek Wrasse. These wrasses are pretty uncommon, but we find them occasionally in sandy bottom areas. The lightning wrasses we sell are around two inches in length. They reach a max size of 12 inches, so be sure your tank is large enough to hold a larger fish. When the lightning wrasses are small, they are mostly a pale bluish purple with a bright yellow along the top of their body and as they become adults, the light blue changes to a very vivid blue and the yellow becomes more intense as well.
This wrasse is mostly peaceful with other fish, but use caution with keeping these fish with smaller crustaceans or fish as they may become a meal. These fish are best suited for fish only tanks. Also, be sure the tank has a tight fitted lid as these guys (like most wrasses) are prone to jumping.
Please Note: Any new fish purchased from us or from a local pet store should to be quarantined. All fish from anywhere in the wild can be possible carriers of bacteria and protozoa that can lead to an infection in your system, so we always recommend that you use some sort of quarantine system prior to adding them to your system. If you have a fish only system and can medicate the whole system, you may not need a separate quarantine tank. If you have a reef system that cannot be medicated, a good ultraviolet sterilization system should prevent any kind of disease outbreak. We medicate our system for bacterial infections and protozoans, but because we don’t always hold our fish for long periods of time, there is no way to be sure all the protozoan cysts have been killed. A little bit of prevention will save you lots of trouble down the line.
