So I've had my betta, Helios, for 7 months now, and he has been very healthy up until the past month or so.
I have him in a two gallon filtered tank and change the water weekly. I usually use:
2 gallons of Poland Springs water
1ml of fungus guard http://www.amazon.com/Jungle-NL025-F...=jungle+fungus
2ml of Prime water conditioner
1tsp of API aquarium salt
I clean out the marbles, silk plant, and inside of the tank VERY thoroughly with scorching hot water to kill any bacteria before I put the water and other ingredients in.
However, having said this, no matter how good I seem to clean the tank, or how precisely I make sure I put in all the right things, as soon as I put him in his tank now he immediately gets a fin rot infection, and I just get the feeling that he's not as happy as I've seen him in the past.
As soon as he gets the fin rot, I usually put him in a small, 1 gallon quarantine tank with no filter and give him all the usual conditioners and salts etc that I give him in the 2 gallon.
What I've seen is that his fin rot clears away much faster and stays gone and he seems to be more spritely overall. But as soon as I think "okay, he's ready to go back to his regular tank now" and put him in, the fin rot will come back immediately, no matter how much I clean out the tank with hot water before hand.
I want him to be happy and healthy and I'm just not sure what the problem could be.
I don't want to downgrade him to the smaller 1 gallon tank for good, but I also don't want him to be sick in his bigger filtered tank.
Does anyone have any ideas about what the problem might be and how I can fix it?
Please let us know,
Kaleigh & Helios
