I'm very suprised Foster Smith's livestock store has this wrong information for the "GloFish" danios.
It says Min. tank size = 1 Gallon ?? I thought my eyes were playing tricks on me.
Danios need way more space to dart about & will nip each other in such small groups. Just because they are a different color than zebra's doesn't mean they require less care. So here we see another fish used as a pretty little "decoration" for greedy freaks.

Here is the "GloFish Kit"...1.5 gallons for 6 of them...The fish and the tank come together
all at once, so they then suffer through the cycling along with hardly any room.
$80 for it! Get the heck outta here FS.
