Pretty awesome, the angels look really good. I can understand why folks might not be too keen on them, though.
I personally really like them because of the original SCIENCE!!! concept behind the original danio Glofish.
The first one that came out was the one that expressed Green Fluorescent Protein (GFP), which is normally found in a certain species of jellyfish. The others that have since come out contain variations of that original gene. They were originally developed to help detect water pollution! The protein has a half-life of about 18 hours. If there is any chemical toxin in the water that affects the health of the fish, their colors will fade because they stop making it (I do not think that heat or pH stress would be enough to cause this to change AS much as toxins). Once they are returned to clean water, they will color back up, since it's coded in their genes, and not injected like those awful dyes that people inject into glass tetras. The change to DNA is a simple insertion for the protein itself, no other changes have been made to the fish. If released, their potential environmental impact is arguably LOWER than that of other danios, because thier bright colors would cause them to be preferentially preyed on.
If you have a family member that you are trying to get more interested in the fish hobby, it'd be worth adding them to a community tank.
