I would keep an eye on there behavior, it changes when laying eggs. Has happened every time in my tank inbetween water changes.
2 days ago saw one of the females running around all over and looked like another female chasing her (probably eating the eggs lol) the one running around had the males sperm in her anal? fins. They were clasped together with white stuff in there. First time I have scene that.
So far I have only scene a total of about 8 eggs, they either disappear within a day or so or hang out and they hatch but Im sure get eaten. Some of the hatching eggs I can see the little cap sticking up. May try and throw a couple in a breeder box. The tank is planted but I dont think its planted well enough to fully hide until big enough.
Oh and I match water change temp, doesnt seem to deter them any but couldnt hurt.
