Giant danio aquariums. The larger cichlids chase and defend their territories against the giant danios, which allows the cichlids to exhibit more natural behavior. As egg-scatterers, danios produce around 300 eggs in a single spawning. They spawn in clumps of plants. A so-called "golden giant danio", sometimes seen, is in reality a partial albino fish. "Devario affinis", "Devario browni", "Devario malabaricus", and "Devario strigillifer" were originally deemed synonyms, but are now valid species. The main component of giant danios' diet in the wild are flying insects. This diet is supplemented with aquatic invertebrates such as worms and crustaceans. In captivity giant danios
Danio margaritatus with a markedly blunt snout, measuring just 2–2.5 cm standard length. The body is about three times as long as it is high. In general shape, it resembles "Danio erythromicron" more than any other known species. This species shows some sexual dimorphism: males have a bright-blue background color (dull blue-green in females), and their fins are more brightly colored. The tail end of their bodies (the caudal peduncle) is also higher than in females. The body is sprinkled with small, pearly dots. The back is bronzy green, and the belly in females is yellowish-white. The gill covers are transparent, letting
