Veiltail
Asymmetrical drooping tail — once the default pet-shop betta before halfmoons.
By the WARN Research & Conservation TeamChecked against IUCN Red List & CITES sourcesLast updated
In brief
The Veiltail betta was the default pet-shop morph for decades — long asymmetrical drooping tail before halfmoon dominance. Its defining trait is flowing fragile fins needing warm filtered water and smooth tanks, with identical solitary male welfare rules.
Veiltail: At a Glance

History & Origins
Veiltail asymmetry dominated Western betta trade before IBC halfmoon standards reshaped breeding priorities. Chain stores still stock veiltails heavily. Welfare campaigns target veiltail sales in cups — heated filtered tanks transform survival rates.
Veiltail Fun Facts
- Veiltail asymmetry was once the only pet-shop betta type in many regions.
- Female veiltails have shorter fins than males but same care requirements.
- Veiltails often cost less than show halfmoons — not less demanding for welfare.

Bettas need heated, filtered tanks
Siamese fighting fish are sold in cups worldwide — yet they thrive in heated, filtered five-gallon-plus tanks with enrichment. Better care starts with honest information.
