Hello and welcome. My name is ***** ***** I’m a biologist with over 40 years of experience keeping fish. I’m sorry to hear about this problem.
Breeders have turned to intensive inbreeding in bettas in order to get the long fins and unusual colors. But another result is that the fish now have weak immune systems. As a result, severe fin rot has become common. In some bettas, the fin rot becomes chronic and has to be treated several times a year.In others, one treatment solves the problem. But in others yet,
Salt is a very mild medication, and can’t deal with fin rot. It needs to be treated aggressively with a strong antibiotic. Kanamycin (brand name Kanaplex) has been found to be most effective against fin rot. It’s worth a try. If you can’t find it locally, here is an online source:
Just follow the instructions on the packaging. Make sure you maintain water quality, and if possible, use a small heater to keep the water around 78*F.If you have more concerns, just let me know. I hope your betta will reach a full recovery.
It’s not severe yet. Almond leaves and salt are not very effective against fin rot. Don’t dose more salt than one teaspoon per gallon of water. You can overdose salt, and it can be toxic. If the almond leaves were a cure, we’d see far fewer deaths in bettas. Not a week goes by that I don’t see a case of a betta whose fin rot has progressed to the point of no return when being treated with almond leaves.
If you can’t get the medications I suggested, check your pet stores for Bettafix. It’s usually not strong enough to treat fin rot, but this is an early case, so it might work. It is a natural remedy that works like a mild antibiotic. If you can’t find it, you can use Melafix. It’s the same thing only more concentrated. You would use it at half the rate in the instructions.
Finally, you could consult a fish vet. There aren’t very many of them, and I only found two in Canada, but if one should happen to be close to you, that would be a good option. Their contact information is here:
