Please for the love of all things betta, listen to them, you need to do 100% water changes every day, you need prime conditioner which cannot be found at walmart, but LPS and petsmart, you will need AQ salt, and you will need to be hoplessly devoted to your fish and its fins healing, now, if your water is unsafe, buy gallon jugs, but NOT distilled, DO NOT get distilled, get dechlorinated, and then you'll need to probably move him to a smaller tank for this whole process, put nothing else but maybe a hammock in the tank because the bacteria will cling to the objects and then you'll have to clean them with distilled vinegar... Your fishes life is in your hands, you should never (i know from experience) bring a fish you cannot properly care for into your home, so from now on either use prime conditioner or dechlorinated water from the store, and those little paper strip tests,although i do use them, they are not very accurate...
And body rot, is awful, i doubt they have much time at all at that point.
Good luck with your fish.
Thanks for the advice. I bought some prime, and I will buy some gallons of water at Wallmart as soon as I get out of school tomorrow. I will then move him into a 1 gallon bowl and do 100% water changes daily. Should I continue adding the triple sulfa to the 1 gallon bowl? (I've done 2 of the 4 dosings, but I will add 2 more if I continue in the bowl.) I think his fin rot is too serious for salt. It literally see a difference in his tail from when I go to bed to when I get up. If I do this, do you think there's a chance I can save him?
How much salt should I use per gallon for fin rot this bad? It hasn't gotten any worse today than yesterday so I think the Triple Sulfa is slowing it down. I'm about to move him into the bottled water now.
Ya it's been 3 days in the salt and his fins are looking good. How long do you think it will take his tail to grow back? He was a beautiful HM with 180 degree spread and the longest tail I've seen on a petstore betta. I really hope it grows back.
