This is to help potential breeders
I recently had a Aquarium Encyclopedia state that oscars are sexualy mature at 12 cm. After reading several books I found this to be a misprint so I took it off my site. Oscars are sexualy mature between 7-12 inches. The Parents and Fry need to be seperated when the fry are free swimming. This is because some oscar parents will eat their fry. While some won't why chance it? oscar eggs are clear when laid...non fertile eggs go white in 24 hours...good ones quickly become amber colored you need a flat rock or piece of slate (which is a type of rock) for your oscars to deposit their eggs on. this is a photo of a soon to be defensive oscar mother |
