Betta with Fin Rot

I got a Betta from a friend in late March. She kept him in a 1 gallon aquarium with no heater and an under gravel filter that did not work because the water level was too low. When I got him I put him in a 7 gallon aquarium with a filter and a heater. A little over a month ago I suspected he has had fin rot since I got him. I did not think about it be for because he is a very dark purple crown tail so it was difficult to see the frayed fins and black edges. I put almond leaves, aquarium salt, and Seachem Stress Guard in the tank and did daily instead of weekly water changes. After a couple weeks I decided to medicate with Seachem Paragaurd because he was not looking any better. I treated him as directed for 7 days. It has be a few week since I finished the medication. The direction said for fin rot to 'treat for 7 day or until infection is clear' the problem is I can't tell if he is clear until his fins begin to grow back. If he is clear, how long will it take for his fins to start growing back? And are there any other signs I could look for to know if he is cleared or not?

It can indeed be very difficult to see on some fish.

Fins that are still affected usually look thinner, softer, may have lost their color. The material is weak, and easily split. This effect progresses toward the body of the fish faster in the soft tissue, leaving the rays to be reduced more slowly. The problem with crown tails (as you know) is that their normal fins look a bit like this already- The rays are long, the skin in between is reduced, and filmy, flowing.

When the disease is gone, for a few days the fins will still look like it is diseased, but this effect will not progress. Fins heal very quickly. Within a few days you should no longer see that 'thin, soft, clear' look.
Some fins grow back white, even if the original fins were some other color. A firm, smooth white is good. A fuzzy, puffy white is bad, a sign of fungus which often moves in on compromised tissue.

Fin rot can be caused by any of several disease organisms. Frequent water changes will do several things:
By vacuuming the floor of the tank you are removing reservoirs of the disease organism (if it is a type that lives off the fish for any time).
By removing the nitrate and other things you are creating optimum conditions for the fish, and less optimum conditions for the disease organisms. Keep up the schedule of water changes while the fish is healing.

Salt is good for most species of fish when they are under stress. When it is time to remove it from the water do this slowly. For example, do water changes with just a little bit less salt each time. It may take a few weeks to a month to remove the salt.

I went ahead and dosed him again. I think his fins are growing back.

I moved him to my dorm room last week and plan to start removing the salt this week. And I will continue to use Seachem Stress Guard to help the healing process. I have recently realized just how bad his fin rot was. I looked at pictures of crowntails online and saw that the rays are all about the same length and on my betta they are all different lengths. some of the rays are a quarter inch shorter then others. I have never had a crowntail before so I thought that was just how they looked. Will his rays grow back properly? if so what is the time line until all the fins are fully healed.

Once the infection is stopped you should start noticing fin growth within a few days, not longer than a week.
I am not sure how long it takes for the rays to grow out by 1/4" or more.
I would certainly be feeding this fish high quality food, perhaps adding vitamins.

The reason I asked how long it would take for the rays to grow back was to help me determine if the infection has stopped, but I know now that it is not. I got a good look at him with just the right lighting and saw that he still has black edges on his fins, so I think I will treat him again for 14 days (next longer dosage period for paragard). I have been feeding him omega one betta pellets and will add freeze dried krill with vitamin E. Also I remembered that fin grow is fairly fast from my Malawi Cichlid days.
