Clown Coris (Coris aygula)
The Clown Coris is a spectacular large marine wrasse that changes dramatically as it matures. Juveniles are especially eye-catching, with a pale body, orange saddles and dark false eye-spots, while adults become far darker and more robust, developing a noticeably heavier head profile. Native to the Indo-Pacific, this species is found around reef flats, lagoon reefs and seaward reefs, usually close to sand and rubble patches. Although juveniles are often sold for marine aquaria, this fish grows into a very large, powerful predator and is really only suitable for very large, mature systems run by experienced keepers.

Bought the juvenile Clown Coris for my reef tank. The colors are vibrant and it’s very active. After six months, it grew significantly and became more aggressive. I now have a larger tank and more space for it. A great choice for experienced reef keepers.

The fish arrived healthy and looked exactly as described. It’s a beautiful sight in the tank, especially when it’s active. I’m aware it grows large and needs a big system, but it’s worth it for the visual impact.

I expected something more manageable, but this fish is quite large and territorial. It’s not for small tanks. I’m happy with the appearance, but I need to monitor its behavior closely.
