Danios are a hardy, lively family of fish that do well in cooler water, making them suitable for unheated tanks. Here are some of the popular Danio species, so you can consider which one would be a good fit for you. Links within each species provide more detailed information on that particular fish
Male Zebra Longfin Danios are generally more torpedo-shaped, while females tend to have a larger belly. Generally, male Zebra Longfin Danios spawn with and remain loyal to one female. A breeding pair should be placed in a breeding aquarium with fine-leaved plants for them to spawn over. Roughly 300-400 eggs are produced and hatch within two days. The fry should be fed small pieces of live foods, such as brine shrimp.
