Phoenix Barb (4.5-5”)

Species Overview

• Scientific Name: Puntius phaenops (may also be referred to as Barbodes or Systomus sp., depending on classification updates)

• Common Name: Phoenix Barb

• Family: Cyprinidae

• Origin: Southeast Asia, particularly Thailand, Laos, and nearby regions (note: rare in the aquarium trade)

• Temperament: Peaceful but active; best kept in groups

• Lifespan: 5–10 years in captivity with proper care

 Habitat

• Natural Environment:
  Found in clear, flowing rivers and streams with sand or gravel substrates and moderate vegetation. Often inhabits lowland river basins, floodplains, and forested areas with rich biodiversity.

• Water Conditions:

  • Temperature: 72–79°F (22–26°C)

  • pH: 6.5–7.5

  • Hardness: 5–15 dGH

  • Moderate current and high oxygenation preferred

 Diet

• Omnivorous:
  In the wild, the Phoenix Barb feeds on:

  • Small insects and larvae

  • Algae and plant matter

  • Detritus and organic material

• In Captivity:
  Offer a varied, balanced diet:

  • High-quality flake or sinking pellets

  • Live or frozen foods (bloodworms, brine shrimp, daphnia)

  • Spirulina- or algae-based wafers

  • Blanched vegetables like spinach or zucchini

  • Occasionally fruit bits (small, soft pieces like melon)

 Maximum Size

• Adult Size: Typically 8–10 inches

• Can grow up to 12 inches in very large aquaria or ponds

 Recommended Aquarium Size

• Minimum Tank Size:

  • 125 gallons (475 liters) for a small group

  • Larger tanks (180+ gallons) are better for adult specimens or groups of 5 or more

• Tank Setup:

  • Open swimming space with moderate flow

  • Smooth substrate (sand or fine gravel)

  • Natural decor: driftwood, rounded river stones, aquatic plants

  • Strong filtration system (they are active and create bioload)

  • Gentle lighting enhances their iridescent colors

• Tank Mates:

  • Ideal with other peaceful to semi-active, similarly sized fish

  • Avoid aggressive species or small, delicate fish

  • Good tank mates: larger barbs, silver dollars, tinfoil barbs, rainbowfish, non-aggressive cichlids

 Notes on Behavior and Care

• Schooling species: Should be kept in groups of 5 or more to reduce stress and bring out best coloration

• Peaceful and non-aggressive, though larger size makes them unsuitable for nano tanks

• They appreciate clean, well-oxygenated water and regular water changes

• Rare in the hobby — captive-bred specimens are preferred to protect wild populations
