I think I have some amore going on here

What size tank are these guys in ?

 

Pairing Oscars are quite interesting actually!

They swim in a "school" with the mate and flutter their fins a lot. They also may do gentle lip locking (still semi-aggressively) and they take turns in feeding time allowing the other to eat.

Males and Females are VERY hard to tell a difference (I sometimes can tell though)... Males tend to be wider and well.... uglier... they are pale in color but have more vibrant pattern... Females are VERY pretty in their red colorations but lack a sharp pattern.... they also tend to be slimmer and shorter than the males...

You know when they are truly pairing when they take turns trying to dig to the bottom of the tank (that action is making a nest)

Oscars spawn on a HORIZONTAL flat surface like a piece of slate or the bottom of the tank. You cant just set a piece of slate in there though.... you have to partially cover it so they can see it is there but they can "clean" it off...

 

Post pics of each one by themselves and 1 of the 2 together and I will give you my opinion for what it is worth

 

That kind of helps.. but you need to know your tubes!

fat and blunt or thin and pointed?

 

Fat and Blunt is a female.... is it your larger colorful one?

 

The darker one is a female.... (I know that is the one you saw the tube on) But by pattern it is a female (the stripes are not well defined)

And my best guess is that the other one is a female too.... They still could pair as quite often 2 females will pair and even spawn... just the eggs cant be fertilized, but one lays the eggs and the other "pretends" to fertilize.

It would also explain why the 2 have not killed each other (2 females or 1 female and 1 male can co-exist but NEVER 2 males)

 

I think they are both female

 

The reason I think the other is a female too is because it has a narrow head BUT age and overall care could affect this... I would say 80% sure its a female

 

Ditto!
