Aquarium Conditions

Most Danios & Devarios are quite active fish and appreciate plenty of swimming space. The larger the tank, the better they like it. If you are intending to keep a number of species, then a tank of minimum size 36 x 15 x 12 inches is required. A well planted tank with an assortment of plants is ideal for these fish. They are not plant eaters so even fine leaved plants will be OK in the aquarium. It is recommended that some water flow is provided; either by the use of an internal or external power filter. These species will often swim against the current as most Danios & Devarios are found in fast running streams. Water conditions are not critical as far as hardness is concerned. They do enjoy clean, clear water. Temperature again is not critical. They tend to like cooler conditions. A temperature of around 65°F to 75°F (18°C to 23°C) is ideal for most species. Some will be quite happy at even lower temperatures.

Danios & Devarios, are generally regarded as "sociable fish" and are far happier in an aquarium if kept in small shoals. A minimum of six fish of each species is recommended. They are not fussy eaters. Live food, in the form of Daphnia, mosquito larvae, Cyclops etc together with the frozen equivalents and dried foods are all eagerly consumed. It is recommended that live foods as above are used to condition the fish prior to attempting spawning. The sex of the fish can usually be identified quite easily. Male fish are slimmer and generally have a greater intensity of colour. Female fish tend to show that they are carrying eggs by their fuller "figure".
