FooF, I give you props! I hate to see fish suffering like that. When I bought my first group of fish for my first tank, one of those was a painted glass fish. I was amazed by it until I started looking up all of the fish that I had.... when I found out it was injected and then found out the process I was appauled. I understand that they look better but it's just plain wrong. Unfortunately my painted glass didnt last long. Back then I had no real knowledge of fish and I knew he was suffering so I ended up putting him to sleep. He was being attacked constantly by the other fish and I had no means or knowledge to quarentine him. It was the hardest thing I had to do so far in my aquarium adventures.
After that experience I have become even more against injecting fish. I wish the non-enthusiast families that just want a tank knew half the things about these fish :sad
