Danio albolineatus common name pearl danio.

They can grow up to 7-8 cm / 3 inches fully grown. They are best kept in water parameters of PH range 6.5-7.5, and temperatures of 17-25 Celsius / 64-77 °F.

The pearl danio is a highly active little fish. They can some times be a little nippy so keeping them in small groups can help as they can nip each other rather than going after other fish.
They can go in to a tank with no heater, but it is recommend to keep an eye on the temperature as if it get to cold for the pearl danio it will get highly stressed.

The pearl danio can be very greedy, so can be first to the good. It is best to spread the food around your tank to try and let your other fish get to some food. They will eat flake, small pellets, and granular foods. Also a treat of freeze dried, frozen, or live foods is good for them to.
