For reasonably equal ratios of sexes in fry, 79/80* f. A majority of the fry produced during fish room winter (72-75*f) were female, summertime spawns (78-81*f) produced fish that were near equal in sexes. Nearly all of the WC fish I’ve seen imported have been male, which would suggest mid-high 80’s durning the end of the natural breeding cycle (low water collecting season)I've been doing some searching on dicrossus fiorni temp range and can't find anything at all that seems reliable. I can't even find good pictures. Anyone know much about this species? Rather get d. filamentosus but fiorni are available.
