Marine Betta (Calloplesiops altivelis)
The Marine Betta is a distinctive and highly attractive marine fish recognised for its dark body covered in bright white spots, elegant finnage and unusual eye-like marking near the rear of the body. Calm, secretive and deliberate in its movements, it is best suited to mature aquariums with plenty of caves and shaded rockwork. Although generally peaceful with suitably sized fish, it is a predator and may consume small fish, shrimp and other vulnerable invertebrates.

I added a Marine Betta to my 120-liter saltwater tank after some research. It’s very calm and hides well in the rock crevices. The white spots stand out beautifully against its dark body. I’ve noticed it occasionally watches other fish but hasn’t attacked any. Great addition to a mature reef setup.

The fish arrived healthy and looks stunning. It’s not very active, which I appreciate since I want a low-maintenance species. The eye-like marking is unique and adds character. Just make sure to provide plenty of hiding spots to keep it safe from smaller tankmates.

After a few weeks, the Marine Betta has settled into its corner and seems content. The finnage is elegant and the white spots are very visible. I’ve kept it with larger, non-vulnerable fish and haven’t seen any predation. A beautiful and peaceful presence.
