I can't find anything on this morph. Are you sure it's not a purple passion danio? The picture is kind of blurry, but yours do have more of that giant danio pattern.
Interesting. I love the coloration of them! Yea, I can definitely see they aren't purple passions in that pic.
And nice set up! Danios and rainbows are so great together. Mine interact very well with each other, expect during breakfast. haha
Sounds nice. What kind of gouramis do you have?
I think jeta is right on the golden giant. My boyfriend thinks they were just an albino morph too. Still, very neat. I've only ever seen regular giants.
Oh, well, I think that's normal to want to hide in the plants. It's kind of what fish do for protection. I wouldn't be alarmed until you can see a different in their eating and interactions with other fish and if any physical problem pops up.
