Answer
Ashley,
First of all you need to start doing water changes once a week. No matter how large the tank (unless you happen to work in an aquarium) that rule will never change. About 30 percent a week will be fine as long as you have a decent filtration system.
Since your temperature is so low I'm assuming you have a goldfish tank (which honestly shouldn't have a frog in it) and your fish will be fine as long as you keep his water clean and start adding either aquarium salt or slime coat replacers. This will prevent infection and help him heal faster.
