Mating Tiger Oscars | Astronotus ocellatus
A pair of breeding Oscars will go through various rituals such as lip locking, also known as jaw locking, you may also notice them chasing each other around the tank, nipping at each other and performing what sometimes looks like a very rough behaviour. Your Oscars may perform all of these strange behaviours, or just a couple. It is quite rare, but sometimes they don’t do any of them. if you do start seeing your Oscars performing these strange behaviours, don’t get too excited, it can often be many months before they actually start laying eggs. A short time before they start laying eggs, one or maybe even two days, they will go off their food. You will have probably observed them acting strangely such as excavating the substrate, as in picking up mouthfuls of gravel/sand and moving it to another part of the tank.
