The Dumbo Ear Purple Mosaic Guppy (Poecilia reticulatus) is a highly sought-after, premium fancy guppy strain prized for its striking combination of oversized, wing-like pectoral fins (Dumbo Ears) and an intricate, marbled or lace-like "mosaic" pattern across its caudal and dorsal fins.
🧬 Key Characteristics & Genetics
• Appearance: Males feature vibrant, metallic dark or platinum bodies transitioning into deep purple, violet, and blue hues on their flowing tails. Females of this strain typically display slightly less intense but beautiful mosaic designs, often showing pronounced blue or marbled tails.
• Age Development: According to user discussions on r/Guppies, hobbyists note that the purple coloration and pectoral fin size continue to develop and intensify significantly as the fish matures.
• Breeding Notes: While pure strains consistently breed true to type, breeders frequently have to cull or separate variations (such as individuals developing unwanted red or yellow mosaic pattern tendencies) to maintain the strain's deep purple purity.
