Firecracker Hi-Fin Swordtail
A selectively bred variety of the Xiphophorus hellerii, the Firecracker Hi-Fin Swordtail showcases a vibrant red to fiery orange body with a long, graceful dorsal fin and a signature sword-like tail extension. This stunning coloration earned it the name “Firecracker”. Originating from Central America’s warm, slow-moving rivers, this tropical swordtail fish is well-adapted to home aquariums and thrives in planted, well-oxygenated setups.
A full-grown Firecracker Swordtail reaches about 4–5 inches (10–12 cm) in length. Males feature the iconic elongated lower tail fin, the “sword”, and an elevated dorsal fin.

The Firecracker Hi-Fin Swordtail is a striking addition to my aquarium. The bright red-orange color and long tail make it stand out. It’s active and peaceful, and it adapts well to a planted tank with moderate water flow. I’ve had it for three months and it’s still vibrant and healthy.

Beautiful fish with a vivid coloration. The sword tail is long and elegant. It’s easy to care for and doesn’t stress other fish. I keep it in a 20-gallon tank with live plants and it’s doing well.

This fish is a true showpiece. The red-orange body and flowing tail are stunning. It’s active but not aggressive. I noticed it swims gracefully in the background, adding visual interest to the tank.
