Is it a common problem with GloFish Danios that they get deformities and die randomly? I started with a school of 12 in my 36 bowfront (was previously a 20 gallon long before I upgraded) and I'm now down to 5... The deaths haven't all happened together or anything, it's been here and there over the last 6 months. Most of them swim fine and eat fine one day, then wind up dead the next, while others start showing spinal deformities over the course of about a week before ending up dead.
The tank parameters are always 0 ammonia, 0 nitrites, and I *think* 20 nitrates max (I have a really tough time reading the nitrate test since it seems like you shine the light on the tube one way it reads one way and shine it a different way it's a different color), all done with the API test kit. I've tried the strips too as a secondary and it comes up 0,0,0.
The best I can figure is that they have less genetic diversity than the wild caught Zebra Danios and therefore are more likely to have deformities... My friend who keeps them in her 60 gallon tank has had similar issues. Any suggestions on what I can do? All the other fish in the tank are totally fine and happy, including my 5 GloTetras (which you think would have similar issues if it's a genetic diversity problem).
