Among the smallest vertebrates on earth, and one of the smallest fishes, members of the genus Danionella are truly tiny, with most fish seldom exceeding a half inch in size. They are more or less transparent, as well, with a slightly amber colour to the body.
The Dracula fish takes its name from a pair of long fangs possessed by males, which are used to spar with one another, sort of like walrus tusks. While the idea of a fish with long fangs sounds really cool, keep in mind the size of this fish -- the fangs are not readily visible to the naked eye.
Due to their incredibly small size, these fish are best maintained in a species tank. They should not be mixed with other Danionella, as hybridization may occur. They may be mixed with other super tiny fish, such as Jellybean Tetras, or with small animals such as most of the small shrimp, micro crabs, or any number of snails.
Their small size makes them somewhat challenging to feed as well. Keep a culture of microworms on hand at all times. They may also eat finely ground flake food or some of the very small micro foods available on the market (especially those designed for fry). Filtration should be a well seasoned sponge filter, as they will be drawn into anything powerful. They will also pick microscopic foods from live plants, filters, and the like.
