Yellow Tux Endlers are prolific livebearers, giving birth to fully formed fry instead of eggs. Males are constantly displaying and courting, and with proper nutrition and plant cover, fry survival is high. Dense vegetation such as Java moss, Hornwort, or Water Sprite provides hiding places for newborns. To maintain color quality and genetic purity, separate lines from guppies and other Endler varieties if breeding intentionally.

💡 Aquascaping & Behavior:
These tiny fish are at their best in a well-planted tank with open swimming space and soft lighting that highlights their brilliant yellow tones. They enjoy mild water flow and thrive in tanks with a balanced ecosystem of plants, snails, and microfauna. Because of their lively nature, they should be kept in small groups of at least 6 individuals to feel secure and display natural schooling behavior.
