are micropredators that naturally feed on tiny insects and zooplankton.

Offer a varied diet including:

Baby brine shrimp

Daphnia

Microworms

Frozen cyclops

Fine micro pellets

Quality nano flakes

Live and frozen foods help enhance colour and encourage breeding. Tank Mates

Their small size means they should only be kept with peaceful nano fish such as:

Chili Rasboras

Ember Tetras

Green Neon Tetras

Pygmy Corydoras

Otocinclus

Kuhli Loaches

Avoid large, fast, or aggressive fish that may outcompete them for food. Behaviour

spend almost all of their time near the water's surface. Males display beautiful extended fins and may spar harmlessly with one another. Keeping them in groups of at least six, with more females than males, helps reduce aggression and encourages natural behaviour. Breeding

These fish are prolific egg scatterers and regularly deposit adhesive eggs among fine-leaved plants, mosses, or spawning mops.

Eggs hatch in approximately 12–16 days.

Fry are extremely small and require infusoria or vinegar eels initially, followed by baby brine shrimp.

Dense planting allows some fry to survive in the main aquarium. Why We Love Them

Peaceful, fascinating, and full of personality, they're an excellent addition to any calm community aquarium.
