I'm a relatively new betta owner, I've had Thomas for a little over 3 weeks, initially in a .5 gallon cube from petco, now I've learned the error of my ways and have had him in a 2.5 gallon tank for the past 2 weeks.

I am concerned that there has been some deterioration of his fins. One of his fins have been curled a bit from the start, but last night I noticed that there seemed to be a tear, a little bit of shredding as well. They just look "different" from when I first got him. I've included pictures, and I tried to indicate with arrows where I believe his fins have split apart. There has also been a small white patch over his nose (also since the beginning)which doesn't seem to fit characteristics of ich? It hasn't grown, or changed, is it just part of him?

Since getting Thomas, he has had 100% filtered water changes weekly, with a heater keeping his tank at approx. 80 degrees. I have been treating water with AQUON betta plus with each water change, and yesterday when changing the water added a bit of aquarium salt. (1/2 tablespoon, for 2.5 gallons) There was one silk plant which I have since removed, as I am concerned it may have been the source of the tear. Thomas does have a plastic hammock leaf, and have purchased anubias and anacharis live plants to replace silk plants.

He is an active little guy, eats 2-3 pellets once a day and does not seem constipated, he is engaging and playful and other than my concerns with his fins, seems alright.

I am not sure exactly how concerned I should be with the slight change in his fins, and if there are additional measures that I should take. Any input would be greatly appreciated! While concerned with his fin, should I do an additional 50% water change during the week?
