My betta, Jerry, recently got a few small holes and a few tears in his rear fin. I want to know what the fin growth will look like. Anyone got pictures? I do not think it is fin rot as it appeared overnight and I keep his water very clean. He is a very active betta. I have heard that getting overactive can cause him to turn his fins ragged and I think that may be what happened. I thought they were supposed to be lazy fish. Is that a common myth or is my betta just an oddball? I usually change his water with 2 days in between water changes. He is in a 2 gallon unfiltered bowl. Since his fin is a little ragged I have added aquarium salt to his water. 2 teaspoons of salt in the water. I have been changing the water daily 100% change since it appeared a few days ago and adding salt with the water change. Anyone with pictures of new fin growth very early new fin growth please post pictures or describe what it looks like in detail. As I have no idea what I should be looking for. On average how soon should I see new growth? How long on average does it take to heal?
