绿咽搏鱼 · Green Throat Mouthbrooder

Overview

The lighter throat pattern of Betta chloropharynx resembles a sideways figure eight and helps distinguish this paternal mouthbrooder from close relatives. Quiet cover and gentle water movement suit it. Companion management changes once incubation ends, so one rule should not be applied throughout breeding.

Distribution & habitat

It was described from Bangka, Indonesia. A population near Palembang on Sumatra once assigned here was later recognized as a different species. Peat swamps and blackwater streams are typical habitat, with heavy shade, low mineral content, acidic water, and a floor of leaves and wood. The clear type-locality pool resulted from human modification.

Aquarium setup

Roots, branches, pots, and tubing provide sheltered spaces. Leaves add cover and microorganisms. Use subdued lighting, tolerant plants, floating vegetation, and mild filtration. A secure lid prevents jumping while retaining a humid air layer, especially important for fry.

Diet & feeding

Insects, small invertebrates, and zooplankton are likely natural foods. Dry products may be accepted after recognition, but offer regular live or frozen water fleas, brine shrimp, bloodworms, or suitable small insects. Avoid overfeeding.

Behaviour & compatibility

A species setup or very quiet, compatible small companions are preferable. Larger or vigorous fishes may intimidate it and monopolize food. Pairs and groups are possible, but fish other than the parents can threaten released fry.

Sexual dimorphism

Mature males show stronger colors, longer fins, and a broader head.

Breeding

After embraces, eggs held against the male's anal fin are gathered by the female and passed to him. Incubation lasts about ten to twenty-one days. Stress or inexperience can cause swallowing or premature release, so avoid disruptive removals during brooding.

Once fry emerge, they may remain with their parents; some reports suggest faster growth this way. Other fishes, including additional conspecifics, should then be removed. Brooding males have also been observed accepting food, so complete fasting is not universal. Fry take microworms and brine shrimp nauplii. Feed small varied portions several times daily, maintain humid air, and change water in modest regular amounts.

Notes

Throat markings are more informative than general body color for separating related species. Air breathing does not remove the developing fry's need for suitable air conditions above the water.
