Ideal for Beginners

The Albino Wrestling Halfbeak (Dermogenys pusilla) is an excellent choice for novice aquarists seeking a captivating, low-maintenance fish. Native to Southeast Asian freshwater streams, this pygmy livebearer grows to just 2-3 inches, making it suitable for smaller community tanks. Their albino strain features a striking white body with red eyes, adding visual appeal without demanding advanced care. Keep in groups of 6 or more to promote natural “wrestling” displays—males playfully spar at the surface, a harmless behavior that earns them their name.

Tank Setup Essentials

Prioritize a tank with ample surface area over depth, as these fish rarely venture below the top foot of water. A 20-gallon long aquarium works well for a small school; add dense floating plants like frogbit or water lettuce for shade and jumping prevention—they’re expert leapers, so use a tight-fitting lid. Gentle filtration maintains calm currents, while optional driftwood or smooth rocks below add structure without crowding. Dense edge planting prevents injury to their delicate jaws during startled dashes. Soft sand substrate completes the natural look.

Water and Maintenance

Maintain stable conditions: 75-82°F (24-28°C), pH 6.5-8.0, and 10-20°H hardness. These adaptable fish tolerate freshwater or slight brackish (SG 1.005) but prefer hard, alkaline water. Perform frequent small water changes (20-30% weekly) to avoid parameter swings, as they’re sensitive to fluctuations. Test parameters regularly with beginner kits for peace of mind.

Feeding Guide

Exclusively surface feeders, offer gut-loaded fruit flies, mosquito larvae, or frozen brine shrimp—avoid flakes at first, though they adapt over time. Feed small amounts 2-3 times daily to prevent waste; live foods encourage breeding.​

Compatibility and Breeding

Peaceful with similarly sized community fish (no fin-nippers or tiny fry-eaters), but avoid aggressive tankmates. Males display vividly during courtship; females are livebearers with 10-20 fry after 3-6 weeks gestation. Raise fry separately on baby brine shrimp.

This hardy, engaging fish brings dynamic surface activity to your tank—perfect for beginners building confidence.​
