The Marine Betta, sometimes referred to as the Comet, is found in rocky crevasses, at depths up to 45 meters. It is a hardy and disease-resistant fish. A predator by nature, it assumes a "head down" position, with its false "eye spot" near the tail resembling the head of a moray eel.

The Marine Betta is not commonly kept in a reef-style aquarium, but it is reported to be safe with corals and anemones, however, it will eat all small fish and shrimp. It is nocturnal and requires hiding places to provide it shelter from bright lighting, being more active at dusk.

When first introduced into the aquarium, live saltwater feeder shrimp should be used to entice this fish to eat. Using live foods such as feeder fish or shrimp will help it adjust. Once acclimated, it can be fed meaty foods and frozen preparations 2-4 times weekly.

Customer Testimonials

Darren Jaramillo Albuquerque , NM
I have kept these with cleaner shrimp, Antenna Gobies, Neon Dottybacks (very small), Bicolor Blennies, and hermit crabs. They have shown no aggression towards any of the above (cleaner shrimp even cleaned it from time to time). I had the shrimp for three years and the Betta for eight. I also kept a Hawaiian Zebra Moray in the tank with them.

I bought mine from Divers Den and have had it for over a year now. It has moved with me twice and is a tough fish. I have had mine with Tangs, Pajama Cardinals and a Snowflake Eel and it is great. Lots of personality. When I approach the tank, he's looking for food. I am very pleased with this fish; thanks Drs. Foster and Smith!!!
