Danios usually stay in the upper to middle regions of the tank and rarely feed from the lower strata. All species of the genus Punitus stay in the lower to middle areas of the tank and rummage the bottom for food. Really good ones to keep are the Cherry barb, Rosy barb and all members from the families Rasbora and Bracydanio . Members from the species Puntius cannot be kept with calm, slow moving long finned fish, as they tend to nibble and nip on the fins. They should be placed in a special tank set up for breeding.
Most species require soft, slightly acid water to breed.
The newly hatched fry need the finest of food, usually newly hatched Brine shrimp or very fine flake food. Breeding Barbs and Danios is not that easy to do and requires time and patience.
