Brandon Cameron –
The male bimaculatus arrived healthy and active. We have a 120-gallon reef tank and it has adapted well. It’s not overly aggressive, but it does defend its space. Good coloration and active swimming behavior.
Dorothy Gibson –
We’ve kept this fish for three months now. It’s calm most of the time but shows interest in the edges of the tank. The tank size is adequate, and it’s a good addition to our community.
Jake Black –
The fish looks vibrant and has been thriving in our 100-gallon tank. We didn’t expect it to be this active, but it’s a great visual addition. No issues with compatibility so far.
