This rare social betta is exceptionally colorful and can be kept communally in a large enough aquarium! It is one of the most colorful "wild" Betta species and is one of the few species that naturally thrives in high-pH, hard water!

Betta mahachaiensis is It is not commonly seen in the aquarium hobby, but is highly sought-after due to its coloration, which is among the best of all "wild" Betta species. Like all labyrinth fish, it possesses an air-breathing organ that supplements its gills and allows it to live in aquatic areas that are poor in oxygen. As with virtually all bettas, males have larger size, longer finnage, and more intense coloration than females. A very unique characteristic of this species, however, is that it is native to a limited area of coastal Thailand and it even inhabits brackish areas. It does not require these conditions, though, and our specimens are USA-bred in full freshwater.

Green Betta mahachaiensis requires an aquarium with dense vegetation and plenty of cover. A darker substrate will result in the most vivid coloration for this fish. Slow to moderate water movement is preferred, so turbulent conditions should be avoided. This fish is typically timid and peaceful with other species, but males can be somewhat territorial in smaller aquariums. This behavior is easily mitigated by providing plenty of space, hiding places, and coverage. This is much less of an issue in larger aquariums. While it is possible to keep this fish with most peaceful invertebrates, it is also possible that it will prey on dwarf shrimp. Due to its timid nature, Green Betta mahachaiensis should not be kept with boisterous or aggressive fish that will outcompete it for food. It might be best kept in a species-only setup, or with very peaceful fish such as small rasboras, Kuhli Loaches, and similar species.

Green Betta mahachaiensis should be offered meaty frozen and live foods at first. Once acclimated to the aquarium, it will likely also accept dry foods as well. Variety is key to longterm health and optimal coloration. Like most bettas, this species will overeat and become obese if given the opportunity
