Good luck

oscars sex can bea easy determined ,first ray of the dorosal fin is short and ended sharply in case of male ,while females got a bit longer ray and ended rounded

Have any proof to back that up? Oscars are monomorphic, meaning you cannot differentiate between the sexes externally. At least, as far as we can tell.
