TMTPOWERS,
Just catching up on my forum surfing and noticed this post about Glofish. I have the same concern with Glofish hardiness. I bought six of them about six months ago. I lost one within the first month but the remaining five seemed very healthy. I noticed how FAT three of them were getting and assumed they were egg bound. About a month ago I was out of town over a weekend, and when I came back, one had dropsy. It was my first case in 30 years of fish keeping and the sight of the fish's scales on end sicken my stomach. I put it in a hospital tank with the appropriate medication, but it died within a couple days. Now the four remaining ones (two still fat as ever) still seem healthy and very active. I want to replace the two that died because the Glofish receive the most compliments from my family and friends (even more than my clown loaches, school of neons, fancy guppies, and Blue Rams). I'm just holding off waiting to see what happens to the remaining four over the next few months.
