1 of my Green cory fins look like someone took bite out of them. He's tank mates are 2 more green cories, 6 zebra danios, 3 upside down cats in 30gal. All other fish fins look fine, I noticed green cory fins about 4 days ago, how long should I give them to start to heal on their own, before I try medication?

Your Zebra Danios are pretty notable for fin-nipping other fish. You may have a repeating problem of this in the future.
Melafix is an all natural, great healing product (uses tea tree oil). Your fish is probably already healing a bit on his own (although slowly) but the Melafix will speed this up. Make sure there is no fin rot (blackening edges) or fungus (fuzzy patches) affecting his fins. Keep the water extra clean.
