Ornate Rainbowfish (Rhadinocentrus ornatus) - Tank Bred

Rhadinocentrus ornatus is native to eastern Australia, where it inhabits slow-moving streams, swamps, and heavily vegetated waters. These environments are typically soft, slightly acidic, and rich in plant life, with minimal current and abundant natural cover.

This species thrives in a planted aquarium that mimics its calm, natural habitat.

Plants: Dense plantings of stem plants, mosses, and floating plants like Frogbit

Hardscape: Light driftwood and leaf litter to create a soft, natural layout

Botanicals: Indian Almond Leaves and seed pods to introduce tannins and encourage microfauna

A calm, layered aquascape with subdued flow allows this species to display its natural schooling behavior and subtle coloration.

Omnivorous. Feed a high-quality micro pellet or fine flake as a staple diet. Supplement with small live or frozen foods such as baby brine shrimp, daphnia, and microworms to support health and coloration.
