Guppies are historically one of the most popular entry points into the aquarium hobby, but designer strains like the Blue Mosaic Dumbo Ear require a basic understanding of water chemistry and care to maintain their flowing fins and vivid coloration.

Unique Physical Characteristics

• Dumbo / Elephant Ears: Refers to the enlarged, high-visibility pectoral fins that ripple gracefully like wings as the fish swims.

• Mosaic Tail Pattern: A dark, webbed or lace-like reticulated pattern overlaid across electric blue, violet, and iridescent silver tail fins.

Tank Setup & Water Chemistry Tips

To keep your guppies active and disease-free, follow these foundational husbandry guidelines:

1. Filtration & Flow Rate: Because of their heavy, delicate fins, Dumbo Ear Guppies struggle against strong currents. Use a sponge filter or a adjustable hang-on-back filter with a low flow rate to keep them swimming comfortably.

2. Water Hardness: Guppies thrive in hard water with steady mineral levels. Avoid using pure reverse-osmosis (RO) water unless it has been re-mineralized.

3. Plant Cover: Adding live plants such as Java Fern, Anubias, or floating Hornwort gives these active fish resting zones and reduces environmental stress.

Dietary Requirements

Feed your guppies a varied diet 1–2 times daily. Small, slow-sinking micro-pellets or tropical flakes should form their core diet. Treat them 2–3 times a week with frozen or live foods like baby brine shrimp or daphnia to boost their immune health and bring out their deepest natural blue pigments.
