i do have different types of oscars at the same tank is it possible for them to breed even they are not thesan\me type of oscar?

yes, provided you've got male female combination.

if you happen to have both male, you will be in
trouble once they matured and try to establish
territorial dominance. if happen to be both female,
there is a big chance that they will get along well,
lay eggs but never fertilized.

you can scroll one posting here about red tiger and
a lutino. there were picture of the parents as well
as the off-springs for your reference.

oscars like people can easily breed within the species. the resulting fry will be a combination of the parents as well the same as the parents( if you breed a lutino tiger and a red you should get a mixture of reds, lutino tigers, red lutinos, regular tigers).
