Angelfish

Angels are the most well-known and popular of all the Cichlids. Their original habitats are the soft, acidic watercourses of the Amazon basin; they need an aquarium with a great deal of space, including depth, where they can swim without restriction. Plants, however, are also essential to form refuges. Angels are peaceful species - except during spawning - and you can keep them with Characins and Corydoras species in a regional South American tank. You should not, on the other hand, introduce smaller species, which the angels are likely to regard as prey. Angels will accept manufactured foods, but they delight in small, live prey, which is the best option.

Pterophyllumscalare

Currently bred both in Europe and Asia, a long way from its native waters, the angelfish exists in a large number of varieties classified according to the amount and intensity of black coloration. Further, there are veil forms of practically every variety, sporting fins that are distinctly longer than normal. Size: 10-15 cm.

sticky eggs on broad-leafed plants (especially those of the genus Echinodorus) or on PVC pipe placed in the tank. She will sometimes choose other, surprising sites, such as the aquarium glass or the heating equipment! The male then joins the female in guarding the eggs and fanning them; hatching takes place in 1-2 days. Sometimes, especially with the first clutch, the parents fail to fulfil their role and ignore the eggs; remove the adults, and imitate their nursing behavior by positioning an airstone or diffuser near the nest: this will stir the water and aerate the eggs.

The fry, which do not resemble the adults, start to feed on Artemia nauplii a few days after hatching. Whether breeding i successful or not, both the parent fish are able to mate again soon afterwards.

Pterophyllum altum

The deep angelfish is caught in its natural habitat, and so is rarer and more expensive to buy. It is distinguished from its cousin by the sharp indentation just above eye level. Its care is not quite so straightforward; the quality of the water must be just right. Size: 1 5 cm. •
