30g West African Coastal Stream

KIllis spawn slowly, and since their eggs (for Aphyosemion and Fundulopanchax) generally take over 2 weeks to hatch and are unguarded, survival rates are low. In single species tanks tanks, many won't eat their young, but their young will eat siblings. There's an interesting thing where fry predation here always appeared to switch off when they reached a certain size.

However, I've noticed a species that doesn't eat its own fry will seem to hunt the fry of another species. Competition...

I've never had a non annual species overrun a tank the way guppies or platys can. Oh, @Back in the fold , if you want fry from wild caught pulcher/kribs, I have well over a hundred from spawn 2, which is smaller than spawn one was. Maybe we can modify a model train set to get them over (under) the border...

I would not keep 2 pairs together. I read once that a calm water kribensis territory in nature could be 9 square metres. The main reason why dwarf river cichlids aren't more popular is the one pair per tank reality.

Well . . . . . as I so often do , I stuck my foot in my mouth there . I never would have guessed ! The one and only time I raised Krib’s I got about 20 fry after waiting on them for over a year .

My other pairs used to give me 40 or 50, but I think with my current softwater, fertility is way higher and these guys are going nuts. It's the first time I've been able to coax wild caughts to breed, and I just can't save and raise the young. They are churning the poor things out, but a local person has the stores covered with a domestic red krib form, and anyone who wants the species can get them for a very low cost. They're a $7 cad fish here, and that's under 5 usd.
There's nowhere for them to go.

Young from wild pairs are special things to me, but to the average hobbyist, colour forms are bigger draws.
