Recently, Aquarists often ask me about the problem of identifying the sex of male and female homomorphic three-lake cichlids, but of course the most accurate is to observe their cloaca. The so-called cloaca are the holes they excrete – the anus and the holes that reproduce – the genitals. The female fish releases eggs through the fallopian tubes in the genitals, and the male fish releases sperm through the vas deferens, these basic fish sex knowledge I think everyone knows. But I find that many friends overlook one of the most important fundamental issues, which is the sexual maturity of fish! In fact, to be able to determine the sex of the fish with relative accuracy, your specimen must be a sexually mature individual! Of course, it is best to have reproductive experience, and the difference in the cloa of male and female fish is even greater, and it is easier to find and judge.
Just when surfing over the wall to learn about the three lakes, I found an article that contained several typical varieties of cloaca "HD" photos! No mosaics! Of course, the author also made it clear that the specimens are all confirmed sexually mature individuals! Share it with you, hoping to help friends identify the male and female who love fish in the family!

Hereby described
NO.1
butterfly
(I feel that the name of the editor on this picture is written incorrectly, kaiser should be what we usually call Caesar Golden Room, but it does not belong to the category of moorii)
In addition to looking at the cloaca, butterflies are mature enough to distinguish between male and female by mouth shape, but Xiaobian feels that this is more difficult, of course, as a reference, you can practice your eyesight!
NO.2
Dragon King
NO.3
Six rooms
NO.4
Phoenix class
NO.5
Pearl Tiger
The figure below is a side view, with mature and breeding females having a clear prominence

NO.6
Half in and out
Editor's Note
What do you think? Have you seen these pictures more dizzy?
Most aquarists must think that the picture is very clear,
Turning back to pick up the fish, I fainted again...
Don't worry, if you observe more, you will also practice the golden eye of fire!
Again: the specimen must be a sexually mature individual!
If you have enough fish, you can prepare three containers!
Fished out of the tank and observed one by one, the male fish put a separate container
The female fish put a separate container,
The other group is, of course, unsure!
When repeatedly observing, be sure to pay attention to the health of the fish!
Don't stay outside the water for too long!
Finally, I wish you to practice the golden eye of fire to distinguish between male and female as soon as possible
