Species in the Genus Paracheilinus
Wrasse Compatibility
The peaceful nature of Flasher Wrasse makes them compatible with other communal fish and wrasse. In general, Flasher Wrasse can be kept with other wrasse, including their own species and other species of Flasher Wrasse when housed in an appropriately-sized aquarium. Even though most Flasher Wrasse only max out around 3", a larger tank is required to accommodate their active and open water swimming habits. This is especially true if you want to keep multiple Flasher Wrasse species together. Other male Flasher Wrasse will encourage bright-colored flashing displays. Ideally, same species or mixed species of Flasher Wrasse should be added together at the same time or added in groups together when housed in the same aquarium. Every fish and every aquarium environment can differ so it is possible you may run into compatibility issues when mixing species or keeping the same species together. This is why a large aquarium is key. Smaller aquariums with established residents may not always accept newcomers. If there are compatibility concerns when adding new Flasher Wrasse to an aquarium with existing Flasher Wrasse many aquarists have had success using an acclimation box. An acclimation box helps the fish get used to each other over the course of a few days. Acclimation boxes allow the fish to eye each other up while preventing "picking", "nipping" or other more severe physical attacks. After a few days when the interest and aggressive displays have subsided, the wrasse can be released into the general population. Be sure to keep a PVC tube, large shell or some sort of structure in the acclimation box for the wrasse to retreat to when needed. Keeping the aquarium lights off or subdued during acclimation is always advised to help mitigate stress.Flasher Wrasse Care
Since many Flasher Wrasse sleep in the gaps and cervices of rockwork and coral structures, substrate or sand is not required. Flasher Wrasse are known to sleep in their own mucous sack or "cocoon" when the lights go out.
