Description
A deep-bodied, slow-moving basslet-relative clad in blackish-brown with dense white spotting and greatly elongated, fan-like unpaired fins; a false eyespot on the rear dorsal lets it mimic the head of a spotted moray eel when it backs into a crevice. Peaceful toward corals and sessile invertebrates but a nocturnal ambush predator that will inhale small fish, shrimp, and other motile inverts. Give it a mature rockscape with caves, subdued lighting, moderate flow, and a tank of calm tankmates that won't outcompete this deliberate, slow feeder; newly imported specimens often need live foods before weaning onto meaty frozen fare.
Reef Safe
With caution
Environment
The Marine Betta prefers a tank with plenty of hiding spots, such as caves and crevices, as it likes to hide during the day and come out at night. It also prefers dim lighting to mimic its natural habitat. The tank should have a tight-fitting lid to prevent the fish from jumping out.
Behavior
The Marine Betta is a relatively peaceful species that tends to keep to itself. It is nocturnal and prefers to hide among the rocks and crevices during the day, coming out to hunt at night. Despite its peaceful nature, it may eat smaller fish and invertebrates.

I have two captive bred marine bettas. I love them. They do disappear for a couple days, but they are pretty small at this time. They have been model citizens and survived all my newbie tank mistakes. I genuinely think they would survive virtually anything.

The one I received was eating right away but they are nocturnal so keep that in mind. They require caves and will stay in them essentially all day. Gorgeous fish tho and I personally love looking at the tank at night when everything has settled.
