Black Angelfish (Pterophyllum scalare) are easy-going cichlids that do well in almost any community tank. They can tolerate a wide range of pH values and are peaceful enough to be kept with most tetras and other peaceful cichlids. Breeding Angelfish can often be achieved by giving them a vertical, flat surface to spawn on, such as a leaf of an Amazon Sword or a piece of slate leaning against the wall. Fry will be cared for until a few weeks after they are free swimming, though you can remove the fry or eggs and hatch them artificially if you wish.
