Zebra Danio
Alternative Name(s):
Scientific Name(s): Danio rerio
Category: Coldwater
Difficulty:
Maximum Size: 5cms
Minimum Tank Volume: 90 litres
Minimum Tank Size: 3 ft
Water Temperature Range: 18-24°C
Water pH Range: 6.0-8.0
Water Hardness Range: 4-15 dGH

General Information: Zebra Danios are lovely fish and good for beginners as they are hardy. They are shoaling, upper region fish who are very enthusiatic swimmers. Not aggressive, but do NOT keep with long finned fish as they are too fast for them and can be fin-nippers. Keep in a shoal of at least 6. In the summer they can be kept in unheated tank.
Tank Requirements: Zebra Danios are very active so appreciate a larger tank with plenty of swimming space.
Diet Requirements: They are very adaptable and will eat most aquarium foods, even goldfish flakes.
Compatibility: They are community fish. Don't keep with slower or long finned fish.
Recommendations: There should be a current in the water. Goldfish will eat small Danios.
Common Problems:
Similar Species: Many related species and colour variants.
Sexing: Females are rounder and usually larger.
Breeding: As soon as the lights go on (real sun or artificial light) in the morning, the Danios prepare to spawn. The males chase the females. Remove adults after spawning.

 Dispute With Temperature
Not sure if I agree with the temperature. I've heard conflicting reports about this; some claim that the zebras will lose more colour when kept at lower temperatures.

Personally I have found higher temperatures between 75 to 80 suit them fine and mine are much more colourful and active then when I kept them at a room temperature between 70 to 74.

As with most fish they will be more active and colourful with a dark substrate as opposed to a light one.

Generally these fish will leave others alone assuming you have at least five; they will be so obsorbed with chasing each other they will ignore any others. Don't worry if they chase other danios, I have never seen them actually harm each other or damage their fins.

 Re: Dispute With Temperature
I would never allow any of my tanks containing danios (I've got several other species too!) rise above 25. I've had danio rerio thriving and spawning in temperatures as low as 17*C. I always struggle in heat waves because the danios actually struggle at the high temperatures. I also found their colour faded and became very slow moving.

I would never expose danios to 80!!!!

Danionins are one of my favourite fish and the ones i have (i think 6 species(soon to get another 4 species)) also find higher temperatures a struggle, especially my wild species.

 Re: Danios, zebra and leopord
Having been the proud owner of some zebra danios for just over a week now, I have a bit of advice for people who may want to have their danios in an open top tank:

THEY CAN JUMP REALLY HIGH!

I nearly lost one of them on the first night after it flipped itself out of the tank, and unfortunately I did actually lose one a couple of days ago after it managed to jump out of a gap in the tank lid that is no more than one inch by two inches.

My group of six became five, but I'm currently having a proper glass lid cut to avoid this sort of thing happening again.
