Name: Zebra Danio, Zebrafish, Leopard Danio, Glofish(TM)
Scientific Name: Danio Rerio
Size: 1.5 Inches
Diet: Flake food is accepted with gusto
Temperature: 20-28'c.
Origin: India and Malaysia
pH: 6.6-8.0
Minimum tank size: 10 gallons, 5 is acceptable

The ultimate starter fish! Small, doesn't make a lot of waste, active, personable and practically invincible, the Zebra Danio has made quite the impact on the pet scene. Available in many colors and types, these little danios will knock your socks off! Tolerant in most cases of ammonia past 2.5 ppm, can cycle tanks for the beginner not used to a fish-less cycle. Active shoalers, these fish should be kept in a group of at least four, at a fish-to-aquarium ratio of about 1.1 fish per gallon (round down). The only downside to this fish is likely it's incompatibility due to it's small size and active, somewhat boisterous nature.

Respectfully disagree with this. They are far too active to be acceptable for a 5gal or even a 10gal. Nothing short of a 20 long is really appropriate for these fish.

I understand that. I was thinking maybe of upgrading it to 10 and 20, I do believe that, if adequately decorated (as most beginner tanks tend to be) a 10 will have enough space for them to move/frolic. IME, having kept both in my 55, Neons are a far more active fish. I do not "promote" the keeping of danios in 10gals in that I would not recommend them, but they are excellent for a beginner, who usually have 10 gallon tanks.

I missed the gun for editing, how do I update articles?

Also, your listed size is lower than any other resource I've seen (they all say 2-2.5", you say 1.5"), and your given temperature range is higher than anything I've seen as well. What are your sources?

Personal experience with the fish for the 1.5", 2-2.5" is more than it seems. I've never seen a danio specimen over 2", and that includes with water magnification. Certain "jumbo" breeds may be larger. My temperature range may be off, I'm rusty with celcius measurement. 68-82 degrees farenheight is what I meant.
