I've had my betta fish, Eugene, for a few months now. Before yesterday, I was changing his water once every month because that was what the pet store manager told me...Now I know better.
I regret putting him through so much stress. I did a 100 % water change yesterday and cleaned everything in his tank. He has torn fins. His colour has also become dull (he used to be a very bright metallic green. Now he is blackish grey.)
I am very worried and I want him to get better as soon as possible. I know I am at fault and I want to try everything to correct it.
I have a 2.5 G tank with a heater, so the temperature is somewhere around 78-80. I removed the filter since it had such a strong current and took up half the tank. I feed him pellets twice a day (4 pellets in a day). I also put aquarium salt in the water along with a conditioner that has stress coat.
If I continue to do 100% water changes every other day, will his colour come back and will his fins grow back? I just want him to be healthy again.
