🐟 Roundtail Betta Fish (Betta splendens)
Freshwater Betta • Solitary Species • Smooth Tail Display • Beginner-Friendly
📋 The Roundtail Betta (Betta splendens) is a graceful betta variety characterized by its fully rounded, circular smooth-edged tail.
Unlike Delta or Halfmoon varieties, the Roundtail’s fins maintain a softer curve, creating a natural and fluid graceful swimming style that is easy on the fish and less prone to tearing.
As with all bettas, males should be housed as solitary fish, as they are territorial and may show aggression toward other bettas or similar fin types.Elegant, hardy, and beginner-friendly, the Roundtail Betta is perfect for aquarists wanting a classic, balanced fin shape with a gentle aesthetic.
