Pterophyllum Scalare are relatively easy to breed, once you have established that you do indeed have a pair. There is no surefire method of sexing these fish by looking at them, so you have to wait for them to decide on the mate of their choice. They prefer soft, acidic water, but they are successfully kept and bred in an extremely varied array of water conditions. The main thing to keep an eye on is water quality.
