BREEDING MOSQUITO FISH!!!!!!!!

[GarFreak]

need help. i need to know how to sex my mosquito fish to know how much i have of each.

The sex can be differentiated as it is for guppies. Males are smaller and exhibit a gonopodium (anal fin adaptation to allow for internal fertilization). Females are larger, have rounder abdomens, and usually exhibit a gravid spot (darkening towards the posterior aspect of the abdomen).

thanks. i think i have all males.... epic fail.

i managed that too- dipped about 20 to get home and have all males. Quite annoying. The sexes don't school together in that river, i guess.

 

[Oddball]

If you netted fry (1/4"-3/8") the males will not yet have developed a gonopodium.

these were 1" plus. They stayed male for another month until I let them go (same river, don't worry).
