So, what should I do about these tears?
I don't even know what he tore his fins on. Maybe he got caught in his plant? I dunno.
Anyways, treating the tears.. Anything I can do other than wait?
Plastic plants and filter intakes are bad for bettas because their fins are practically gossamer. Pretty, but high maintenance.
As for fin-rot...unless it looks like the fin's melting or has red/black on the edges where it's torn, it's more likely just a tear or he's a tail-biter
My VT is a notorious fin-biter. He literally swims in a circle chasing his tail and bites his tail. The reason? No one really knows.
Sometimes it's associated with stress, boredom, or even left over aggression.
For finrot: aq salt and 100% water changes for a few days until you see new growth (it'll be white'clear but clean)
For torn fins: can put new pantyhose around the filter intake with an elastic (no metal on it), replace plastic plants with silk ones, including trimming off any plastic thorns. To test how sharp a plant is, run it over nylon. If it catches or tears the nylon, it's bad for your betta.
Tail-biting: Some people advice adding regular stress coat+ to his water changes so that if he does bite his tail, he has the proper additive to keep it clean and help it grow again. AQ salt works great too. I'm currently using both since he seems to be a in a 'mood' this week. Also, I change around his tank decor every two water changes to keep him entertained with 'new' scenery. And then I also make sure to have flaring exercises with him (I do it for all of mine really, but his is the most important). My little Phy is aggressive and gets bored sometimes, so I just hold a mirror up to him to flare at for a minute or two then slowly pull it away, letting him 'win' the contest. I'll do it a few times an hour, maybe 2 or 3, 4 max. Then he'll patrol is tank, flaring and being the king of the tank and he doesnt have another biting episode for at least a few days to a week.
In all of these cases, the aq salt helps the wound stay clean and helps re-growth. keeping the water clean will help keep fin-rot away. Phy gets a 50% and 100% water change weekly, about 3 days apart. Same with Demi in her 3g. I would do maybe a 30-50% for a 5g, and my 10g gets 50% once a week unless I thin something's wrong with it. But clean water helps keep out most infections without the help of additives.
Sorry for the long response, but I hope it helped!
Hope this info helps, sorry for the long post.
