🏠 Tank Requirements

These fish are sensitive to water changes and poor water quality—stable parameters are key.

🍽️ Diet

• Type: Omnivore (micro-predator in nature)

• Best Foods:

  • High-quality micro pellets or nano flakes

  • Frozen/live: baby brine shrimp, daphnia, microworms, grindal worms

  • Occasional vegetable matter: spirulina flakes, crushed algae wafers

Feed small portions 1–2 times daily. A varied diet enhances color and breeding behavior.

🤝 Tankmates

CPDs thrive in peaceful community tanks with soft water and gentle companions.

❤️ Health & Lifespan

• Lifespan: 3–5 years with proper care

🥚 Breeding

• Breeding Type: Egg scatterers

• Breeding Behavior:

  • Males court females with fin-flaring displays

  • Females scatter eggs over fine-leaved plants or moss

• Spawning Tips:

  • Use a separate breeding tank (5–10 gallons)

  • Add Java moss or spawning mops

  • Keep 1–2 males with 2–3 females

• Egg & Fry Care:

  • Adults may eat eggs—remove parents post-spawning

  • Eggs hatch in ~3 days; fry swim freely after 2–3 more

  • Feed fry infusoria or powdered food, then baby brine shrimp

CPDs breed readily in aquariums but fry are tiny and delicate.
