Never experienced this before. Today I bought 6 Cardinal Tetras, and when I got home I noticed the water in the bag had a blue tint. I didn't notice this in the store. I did some research and it seems that adding Methylene Blue disinfects a fish tank, and actually tints your water blue.
Wtf? Did they sell me sickly fish?
