About this fish

Praecox Rainbowfish is a stunning pick for planted aquariums, chosen for their vivid neon-blue body, active schooling behaviour, and peaceful personality.

Why you will love it

  • Brilliant electric-blue colouration with orange-red fins on males
  • Approx size in store: 3 - 5cm
  • Active mid-water schooler that brings life and movement to any aquascape
  • Community (peaceful; ideal with other small, calm species)

Care requirements

  • Care level: Easy
  • Adult size: 6 cm
  • Temperature: 22 to 28°C
  • pH: 6.5 to 7.5
  • Swimming level: Middle to top
  • Minimum group size: 6+
  • Substrate: Any; fine gravel or sand suits their natural habitat

Feeding: Offer a varied diet. A quality staple (flake or micro-pellet) plus frozen foods (brine shrimp, daphnia, bloodworm) several times per week keeps colour and condition strong.

Compatibility: Best with peaceful, similarly sized tankmates. Avoid fin-nippers and aggressive species. Excellent companions for tetras, rasboras, corydoras, and small plecos.

School of Scape quality: We select healthy fish and recommend gradual acclimation and stable parameters for best results.
