[Ebook] The New Guide to Aquarium Fish – Ciclilids – GROUPS OF CICHLIDS – South American Dwarfs
These are small cichlids (up to 10 cm/4 in) from still or slow-moving streams and pools in rainforests and savannahs east of the Andes; their range, and consequently general biotope conditions, coincides to a large extent with= that of the larger species covered above. All are seasonal substrate brooders; most are strongly sexually dimorphic in size, coloration, and finnage, with the male the larger, showier fish.
