I bought 5 fish from and reputed LFS and thinking they are healthy. I bring them home a two of them never eat anything and die later (Magnificent Foxface die in 5 day and powder blue Tang die in 7 days). Also the orange spot diamond goby die on last Friday, he jump out of the tank and I saw him dried up after work. I have around 8 other fish in the tank and they are eating and doing well. Anyone experience this before?
