  • Lifespan: 2–3 years
  • Temperament: Peaceful but mildly territorial, especially males 

Tank Setup

  • Minimum Tank Size: 10 gallons for 1–2 crayfish
  • Substrate: Fine sand or basalt (preferred for growth and comfort) 
  • Decor: Caves, driftwood, leaf litter, live plants (they don’t destroy plants like larger crayfish)
  • Filtration: Gentle flow; sponge filters are ideal for breeding tanks
  • Lighting: Moderate to low
  • Lid: Required—they are escape artists 

Water Parameters

  • Temperature: 65–75°F (18–24°C)
  • pH: 6.5–8.0 (ideal: 7.5–8.0)
  • GH: 3–18
