Bought this Altevelis Betta for my 50-gallon reef tank. It’s been thriving for three months. The fish is calm and doesn’t bother other inhabitants. Spots are distinct and it looks healthy. Easy to care for and fits well in the setup.

The fish arrived in good condition and has adapted well to the tank. It’s peaceful and doesn’t chase other fish. I appreciate the clear labeling of care requirements. Would recommend to reef keepers with moderate experience.

Great addition to my marine tank. The size is as described, and it’s very active without being aggressive. The tank is now more balanced with this species. No issues with compatibility so far.
