Red Hi-Fin Swordtail

Feeding
Omnivorous with a vegetable requirement. Flake with spirulina content, algae wafers, blanched vegetables and frozen foods.
Compatibility
Generally peaceful but active and fairly large for a livebearer. Males can be pushy with each other, so keep either one male or several, never two. Needs swimming length.
Behaviour and personality
Strong, purposeful swimmers that use the full length of the tank. Males display with the extended lower tail lobe that gives the fish its name.
Before you buy
Needs more space than platies or guppies and will jump, so a lid is essential. Hard alkaline water required.

The Red Hi-Fin Swordtail is a striking addition to my tank. Its bold red color and extended tail make it stand out. I feed it a mix of spirulina flakes and blanched peas daily. It swims actively and displays its tail lobe when interested. Needs a large tank and a lid, which I have provided. Very satisfied with the fish.

This fish is vibrant and energetic. I kept one male in a 55-gallon tank with plenty of open space. It doesn’t get aggressive and enjoys swimming near the surface. I feed it a balanced diet with algae wafers and frozen bloodworms. It’s a great choice for a bold, active community fish.

The color and movement of the Red Hi-Fin Swordtail are impressive. I noticed it extends its tail lobe during courtship displays. It’s active and requires a well-maintained tank with hard alkaline water. I’ve kept it for over six months and it’s thriving.
