My betta, which I left at home for 3 days while I went on vacation, looked a little sick when I returned. He just did not look normal, and was much colorful and happier before.
1) New betta from Petco, very lively when I first brought him home
2) 2.5 betta tank, quick-cycled using Nutrafin cycle
3) Water conditioned
4) Ammonia was a little high after I got home. So I did a 50% water change immediately. I also put some extra prime in the water itself to lower the existing ammonia.
5) Ammonia, nitrite, nitrate, all normal now. PH is 8.5. Temp is constant 78 degrees.
Based on what he looks like in the picture, what should I give him for medication/treatment? He's exhibiting symptoms like listlessness, floating at the bottom of tank, or near surface of water, hiding/lying sideways inside an empty shell on the bottom of the tank, wont eat / tries to eat but then spits out food, clamped fins, and looking paler than before.
What should I do now?
I've attached a picture.
