  • Obligatory air breather (ref: Wiki)
  • Some 5,000 to 6,000 stacked electroplaques are capable of producing a shock at up to 600 volts and 1 ampere of current (600 watts) (ref: Wiki)
  • There is a male-biased sex ratio, (3:1) (ref: redlist)
  • Males are considerably larger than females (but fishtank wrongly says that males are much smaller than females) (ref: redlist, fishtank)
  • Eggs are deposited in a foam nest built by the male, using his saliva (ref: Wiki)
  • Males are much more abundant (ref: AssuSchw1995)
  • Stomage of 7 cm larvae only consists of eggs, that of 8 cm for 80
  • Young leave the nest at 8-16 cm (ref: AssuSchw1995)


  • Author_mod_1: I found information on the number of eggs per female as a function of length in Anon2013 that was much higher than in Anon2015 but chose to not include it as the temperature was not provided
  • Author_mod_1: I was surprised to observe that the weight coefficient for ab changed so much the parameter values
