Emerald-Green Betta

One of more than sixty species of Betta, the Emerald-Green Betta, also called the Emerald Betta, is relatively uncommon in the aquarium trade. These fish are native to the slow-moving waters of rice paddies, swamps and ditches in northeastern Thailand. In their natural habitat, Betta fish must be equipped to survive in water that contains relatively low oxygen content. To surive in this environment, Emerald Bettas have a special organ called a labyrinth which enables the fish to breathe air at the surface of the water.

Tank Set-Up

Emerald Bettas prefer heavily planted tanks decorated with driftwood roots and small clay pots. Because they are naturally found in sluggish waters, filtration in an Emerald Betta tank should produce low water flow. These fish may also enjoy the addition of some leaf litter to simulate their natural environment. The males of this species can be very aggressive and are thus not recommended for a community tank.

Feeding

These Bettas are carnivorous by nature, feeding on insects, small invertebrates and zooplankton in the wild. In the home aquarium, Emerald Bettas will generally accept dried foods. Offer your Betta high-quality Betta pellets as a staple diet, supplementing it with small live foods such as bloodworms, Daphnia and Artemia.

Breeding

Emerald Bettas are best spawned in a species tank as long as plenty of cover is provided for the female. Raising the temperature in the breeding tank may encourage spawning and once the process has started, spawning may take several hours. Following spawning, the female should be removed from the tank and the male will care for the eggs until they hatch. Hatching typically occurs after 24 to 48 hours and the fry will become free swimming after another 3 to 4 days.
