Care Guide

Diet

Veiltails are carnivorous and require high-protein foods including quality betta pellets, frozen bloodworms, and live brine shrimp. Feed small amounts once daily, only what they can consume in 2-3 minutes, as they are prone to overeating and constipation. Occasional fasting days (once weekly) help maintain digestive health.

Behavior

Veiltails are semi-aggressive surface dwellers with curious, interactive personalities that make them engaging pets. Males are highly territorial and will attack other males on sight; females can be aggressive toward each other and smaller fish. They are labyrinth breathers and must have access to the water surface for air.

Breeding

Breeding veiltails in captivity is moderately difficult and requires careful conditioning of both sexes with high-protein foods for 2-3 weeks prior. Males build bubble nests and will embrace females during spawning; fry are tiny and require infusoria or liquid fry food for the first week. Separating fry by sex at 3-4 weeks is essential to prevent aggression.
