The Leopard Danio is not found in the wild at all. It is believed to
be a cross between the Zebra Danio ( Brachydanio rerio ) and possibly the
Spotted Danio ( the Brachydanio nigrofasciatus )although this is also much in
question. Regardless of its origins it is a beautiful little fish that is very
lively and peaceful towards its tank mates. It is much like its close relative
the Zebra Danio in its requirements, not fussy about its water properties, but
liking clear flowing water. It too likes to be kept in a small group of not less
than six, and loves live food although it will accept anything small enough to
go into its mouth.
The water temperature should be kept between 18-24 C (64-82 F) for optimum health.
The Leopard Danio is an egg layer, but like its relative the Zebra Danio, will readily devour its own eggs unless they are protected. This fish will breed easily, and when the eggs are protected from the parents, proves to be very prolific.
I recommend this fish for a community aquarium, and for beginners and experts alike.
