Feathertail Betta

Betta splendens

AnimaliaChordataActinopterygiiAnabantiformesOsphronemidae

Variety of Halfmoon Betta · Feathertail

📍 Southeast Asia (captive-developed)

Ask Finn

Elaborate mutation where the caudal fin rays branch repeatedly, creating a lacy, feather-like appearance. Arguably the most ornate betta type. Requires pristine water as the delicate fins are prone to tearing and infection.

Care Guide

Diet

Feathertail Bettas are strict carnivores requiring high-protein foods such as frozen bloodworms, brine shrimp, and daphnia 5-6 days per week. Supplement with quality carnivore pellets formulated for bettas. Feed small portions once daily, removing uneaten food within 2-3 minutes to maintain water quality.

Behavior

These bettas are semi-aggressive and highly territorial, especially males, requiring solitary housing or careful monitoring in community tanks. They are active top-dwellers that display elaborate fin flaring and courtship behaviors. The delicate feathered fins make them less aggressive swimmers than standard bettas, and they may be stressed by aggressive tank mates or strong water currents.

Breeding

Breeding Feathertail Bettas in captivity is difficult and rarely attempted by hobbyists due to the complexity of conditioning pairs and the fragility of the elaborate fins. Males build bubble nests and will guard fry aggressively, but the delicate fin structure makes breeding and rearing challenging. Success requires pristine water conditions, separate breeding tanks, and careful fry management.

Common Diseases

Fin Rot

Symptoms

Fraying, discoloration, or deterioration of the delicate feathered fin rays; may appear white or black at edges

Treatment

Perform 25-50% water changes every 2-3 days, maintain pristine water quality, and treat with aquarium salt (1 tsp per gallon) or antibacterial medication if severe

Ich (White Spot Disease)

Symptoms

Small white spots on body and fins, lethargy, increased scratching against surfaces

Treatment

Raise water temperature gradually to 28-30°C, perform daily water changes, and treat with ich medication or salt therapy for 7-10 days

Velvet Disease

Symptoms

Fine golden or rust-colored dust on body, clamped fins, rapid gill movement, lethargy

Treatment

Increase temperature to 28-30°C, reduce light exposure, perform daily water changes, and treat with copper-free medication or salt therapy

Fin Damage from Tearing

Symptoms

Torn or split feathered fin rays, bleeding or open wounds on delicate fins

Treatment

Isolate in a calm, low-flow environment, maintain pristine water conditions, and treat with antibacterial medication to prevent secondary infections
