I have a pair of oscars that mated and I removed all the other fish out of the 125 gallon tank they are in so they can breed. I have placed a nice big flat rock in the tank and they haven't moved away from it since then. I have noticed what I believe to be there sexual organs protruding from the anal opening and am wondering if this is what I am seeing and how soon I can expect eggs. Anyone know what I should expect and how soon???
