Rusty Cichlid Breeding

Postby djlynn03 » Thu Oct 15, 2020 12:11 am

Two of my Rusties just started breeding, but it appeared that the female would lay the eggs and the male would immediately put them into his mouth. Would they still be able to be fertilized or his he just eating them?

Usually the female lays the eggs on one circle. The male follows in the circle and shimmies over the egg to fertilize it. On the next circle the female picks them up.

If the male picked them up, he ate them. Maybe that was the female? Is there a bulge under her chin?

In 7 days if the bulge is still there, that is the female and they are likely fertilized. If they were not fertilized she will likely spit them out or swallow them before the end of 7 days.

There might be a slight bulge under her chin but it’s nothing very obvious. One of them was definitely shimmying in the nest but i did not see any eggs. They may have just blended in to the substrate.

Are you sure that the two fishes who participated in this little ritual aren't both females? :o

They could both be females, they both only have one egg spot. One of them chases the other around somewhat frequently, but other than that they are very similar.

That would be my guess. The females of many cichlid species will pseudo-spawn with each other in the absence of males.
