I bought 2 silver sharks 2 weeks ago. The last couple of days 1 isn't eating and its fins are cracking. The other one is fine. Any ideas why?

If the water quality is poor or improper low water temperature, it will cause fins to split. Also outdated food, possibly over feeding, or moving a shark will also cause fin rot.
As for not eating, the fish may need different food to give it a different taste.
