The Red Flasher Wrasse has become a highlight in my reef tank. The colour change when it displays is stunning and adds a dynamic element to the aquarium. I’ve kept it for over six months and it’s still active and healthy with proper feeding.
Fiona Hudson –
It’s a beautiful fish with bright red and blue patterns. I noticed it extends its fins during the day, especially in the morning. It’s not aggressive and coexists well with other reef fish, though it needs a well-established tank.
