The Red Tail Flasher Wrasse (Paracheilinus rubricaudalis) is a small flasher wrasse known for a red tail accent and quick “flashing” fin displays, especially when it’s aware of other wrasses in the tank. It’s collected from the tropical Pacific, including areas like Fiji and nearby island regions.
What You’ll Observe:
- Short, fast dashes into the open water column, then a return to rockwork “checkpoints”
- More color and fin extension during late-day lighting and around other active swimmers
- Confident midwater feeding once it recognizes your feeding routine
- Nighttime resting tucked into rock crevices rather than burying in sand
Provide open swimming room with plenty of live rock branches and crevices so it can move between shelter and the water column. Offer small meaty foods in modest portions more than once daily to match its active routine. In mixed-wrasse tanks, many hobbyists add more passive fish first so the flasher settles into the community smoothly.
Will a Red Tail Flasher Wrasse “flash” if kept alone?
Many will still display at feeding time or during lighting changes, but hobbyists often see more consistent flashing when there’s another flasher/fairy wrasse present.
Does it need sand to sleep?
Most flasher wrasses wedge into rock crevices to rest at night, so rock structure matters more than sand depth.
Can I keep multiple flashers together?
Mixed-species groups are common, but hobbyists typically aim for one male per “look-alike” group and use extra space/rockwork to spread out attention.
Do I really need a lid?
Hobbyists repeatedly report wrasses finding tiny gaps over time, so a tight-fitting lid (including overflow and feeding openings) is part of normal long-term setup planning.
Why does it change color so much day to day?
Color intensity often follows social rank, nearby tankmates, and routine “display moments” (feeding, dusk lighting), so variation is normal as it settles in.
Each fish is checked for strong appetite and activity before we approve it for your tank.
