Discussion

  • CowlShir2006 reports egg diameter of 3.8 mm, and CaldFalc2019 even upto 5.2 mm, while Wiki reports hatching within 1 d; this is inconsistent with LN data. This entry assumes that extra water contributes to egg huge size and operational egg diameter is 0.9 mm
  • Mean temperature is guessed

Facts

  • length-weight: W in g = 0.00708*(TL in cm)^3.08 (Ref: fishbase)
  • length-length from photo: SL = 0.81 * TL (Ref: fishbase)
