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".
