They will be pure convicts with some white or short body ones thrown on there.
I say that because jellybean parrots are in fact…just shortbody convicts. You can see this in the mouth, parrots have screwed up faces while jellybeans, polar blues, etc. do not.
Congrats on the spawn! There will be some aggression but as long as tank size is sufficient I’m sure the oscars can handle it.
My convict and blood parrot pair (infertile parrot = no offspring) set up shop in a small part of the tank and don’t really leave, giving room to the other fish. They just get mad of anyone approaches.
