Pseudomugil inconspicuus is a small, somewhat understated blue-eye from coastal Queensland, Australia, that lives up to its name in that its initial appearance can seem less vivid than some relatives. However, in a well-maintained planted aquarium under appropriate lighting, the intricate detail of the fin patterning — delicate yellow and grey markings, iridescent eye, and lacy fin margins — becomes apparent and the fish is genuinely beautiful in a refined, subtle way.
This species inhabits the coastal plain streams and wet season floodplain pools of the Townsville to Cooktown region and is adapted to moderately warm, slightly acidic to neutral, soft to moderately hard water. It is considered more sensitive than the robust Pseudomugil signifer and requires careful attention to water quality. A heavily planted nano or species aquarium with gentle filtration suits it best.
Pseudomugil inconspicuus is infrequently available in the hobby and is most commonly found through Australian native fish societies and specialist breeders. It is not particularly difficult to breed but requires pristine water conditions for long-term health and reproduction.
