Oscar breeding

[Kelly_Aquatics]

Hello I have two oscars about 8 inchs in a 125 gallon they are showing what I believe to be pairing behavior
I was just wondering what is the youngest/smallest they would spawn at? And has anyone discovered a reliable method to determine gender of the oscars?

I’d assume venting the oscars.

I've read that the Oscar has to fully Mature before spawn.

ok so they have s[awned for the second time first time they ate the eggs I think because I added a divider which stressed them out ad now they are slowly one at a time eating the eggs now what should I do remove the parents? will the eggs still hatch???

here is a pic the eggs dont look fertile but they just spawned so it might take a while and you can see how angery the big male is lol so that makes me think they are still attached to the eggs and feel they need to be protected?? also I noticed the eggs they were eating were kinda on the outside of their territory so are they js trying to keep the eggs in one location?

The parents especially the female will eat the bad infertile eggs.

ok how long does it take before you can tell if they are fertile?

ok so they just spawned for the like 4-5th time and it looks to me like the male is fertilizing them I will post a vid he is like cupping himself around the eggs and shaking which is what I have seen my other male cichlids do when fertilizing eggs

Sexing them is easy. The female is the one laying eggs. (Sorry, I had to...)

Personally, I like to give newly breeding Cichlids several chances without my interference. They'll often figure it out on their own, making my job easier.

As she gets the hang of things, she'll learn to keep the eggs in a tighter clutch. That makes it easier for the male to spread his love across the whole group. Unfertilized eggs will remain white, fertilized eggs will turn reddish brown. As mentioned, they'll eat infertile eggs as they will mold and the mold can harm the fertilized eggs near them.

What decor is in the tank? If they have high water flow in their area that may make it harder to keep the eggs together as well as to fertilize them.

Here is the video I will get full tank pics but their is minimal decor
