Well, they probably overfed, as that's what they tend to do, right? So extra water changes and spare feeding might correct it just as quickly. That's what I would try first. If that does not succeed, you can go from there.
On the other hand, if they didn't feed at all, it might just need some extra food (nutrients) to correct the imbalance. Either way, restore balance and the tank should improve.
