Aquarium Advice Addict
Max about 1.5 inches. They are more slender then a Zebra danio.
We've kept and sold Danio roseus that were 2" plus. Here's one of our Aquabid photos of 2"+ roseus. They're quite active and adults are a good bit larger than zebra danios. Daileene: unfortunately, this is not a species I'd recommend for a 10 gallon. 20 gallon is pushing it IMO.
