Thanks. my gramma died and my water perameters are great. There was no sign of illness. I got him from a friend and that person had his tank for five years, so I'm not sure how long he had the gramma, but it was at least 2.5 inches long, so it may have been old.
All my other fish are fine, but I just bought a mandarin and he is rather large, so he may be old. I will have to stock copepods regularly to keep him wall fed, but I think he's old.
Thanks.
