Bought this for my 100-gallon tank. The male bluehead wrasse was active and colorful. It did show aggression toward smaller fish, so I removed a few shy species. Works well in a larger tank with plenty of hiding spots. Good for experienced aquarists.

Arrived healthy and looks vibrant. I noticed it was quite active and aggressive, especially during feeding. I made sure to keep it with larger, hardy fish. Not recommended for beginners due to its behavior.

Great addition to a well-established tank. The color is striking and it stays active throughout the day. Only issue is it needs a large tank and careful species selection to avoid conflicts.
