Care guide
Keeping Radiant Wrasse healthy in a South African setup.
Tank setup
A minimum 200L aquarium suits Radiant Wrasse. Match décor to its natural habitat: planting, rockwork or open swimming room as needed.
Water parameters
Keep pH 8.1–8.4 and 24–27°C. Stable parameters matter more than chasing perfect numbers; acclimate new arrivals slowly.
Feeding
Carnivore — meaty frozen foods. Feed small amounts it clears in a couple of minutes, and vary the diet.
Behaviour
Active; sand-sleeping. Watch it at feeding time and at lights-out to see its real temperament in your tank.
Tankmates
Choose tankmates of similar size and temperament with the same water needs. Avoid fin-nippers and anything large enough to eat it.
Breeding
Breeding success with Radiant Wrasse depends on the line and water chemistry; ask your shop about proven pairs.
