I posted on here before about my new girl, but now that I think I may have a lead on what the problem is, I'm posting this new thread in hopes of clear answers.
Ok, so my new girl I got last Friday, Rosemary, suddenly got sick within the days I had her. She was perfectly fine the first day, then acting odd by the 2nd, then the next day clamped fins, and barely moving, and now at this life of being unbalanced, laying at the top or bottom most of the times, no eating, etc.
I've never had a sick betta before, so I'm...very new at attempting to heal her with whatever she has going on in her.
Rosemary is swimming at times but mainly lays on the ground or floats at the top. Clamped fins as well. Today I noticed that she was tilting a lot- either head first or butt up. When she swims, she looks a bit odd but hyper, but will suddenly stop moving, then go about her business floating at the bottom. Breathing looks odd but I may be misjudging that.
I moved Rosemary out of the split 10 gallon into a 3 gallon heated tank.
Water: tested perfectly fine, is treated with the conditioner I've always used, nothing else added.
I honestly think I'm running out of time on her. Just when I thought she may just get better, I see her today just...ugh.
