Update on the
Enantiopus melanogenys spawnings- The second brooding female released her fry last night, and this morning I moved both females back into the
E. melanogenys colony. There seem to be ~20 fry from the two females, which is fairly typical for young females at this size (6-7cm). The fry ate flake food powder from the outset, and today they got their first feedings of live baby brine shrimp. Here are four of them, each ~0.75cm in length.
E. melanogenys is primarily a bottom-dwelling species that is widely distributed throughout the ~1100 mile Lake Tanganyika shoreline.
One of my 'fancy' brine shrimp hatcheries-
I presume that this dominant male contributed to both broods, and although he is the largest male in my colony at 9-10cm, two other males have also constructed nests, and may well have fathered some of the fry.
E. melanogenys females in the wild generally mate with multiple males per spawning, and incubate multipaternal broods. It's one advantage of the lek mating system, which contributes to the genetic heterogeneity of the species.
