The Platinum Halfbeak (Dermogenys pusilla) is a unique freshwater livebearer known for its slim body, shiny platinum-silver coloration, and distinctive elongated lower jaw. This surface-dwelling fish adds unusual movement and interest to planted aquariums and peaceful community setups.

Why Choose Platinum Halfbeaks?

Platinum Halfbeaks are a standout choice for aquarists who want a peaceful but unusual fish for the upper level of the aquarium. Their silver coloration and elongated lower jaw give them a distinct look that is very different from common livebearers, tetras, and rasboras.

They are active, surface-oriented fish and do best in aquariums with open space at the top, gentle surface movement, and calm tankmates that will not outcompete or harass them.

Ideal Tank Setup

Platinum Halfbeaks do best in a stable, fully cycled aquarium with open surface swimming space, live plants, and peaceful tankmates. Floating plants can help them feel secure, but the surface should not be completely covered since they need room to swim and feed.

A secure lid is strongly recommended because halfbeaks are known jumpers. Avoid sharp decor near the surface and maintain clean, stable water conditions for long-term health.

Compatible Tankmates

• Peaceful tetras
• Rasboras
• Corydoras catfish
• Otocinclus
• Small peaceful gouramis with caution
• Peaceful livebearers
• Snails
• Shrimp with proper cover

Tankmates to Avoid

• Aggressive fish
• Fin-nipping species
• Large predatory fish
• Very boisterous surface feeders
• Fish that may harass their delicate jaws
• Very small fry or tiny baby shrimp if predation is a concern

Diet & Feeding

Platinum Halfbeaks are omnivores that feed primarily near the surface. Offer floating pellets, quality flakes, freeze-dried or frozen foods, baby brine shrimp, daphnia, bloodworms, and small live foods when available.

Because they feed at the top, floating foods are especially useful. A varied diet helps support healthy growth, activity, and overall condition.

Care Tips

• Keep in groups of 4 or more when possible
• Use a secure aquarium lid to prevent jumping
• Provide open surface swimming space
• Offer floating foods and small frozen foods
• Maintain stable water conditions
• Avoid aggressive or fin-nipping tankmates
