Ok so I tested my water when I got back, it was around 1.0-2.0 so I added more and this morning its reading .5 so I'm guessing either my tank is cycled OR my test isn't reading correctly.
ALSO I decided to go ahead to Petland to go check to see if they still had the girl I wanted. Well when I got there I found this

She was being eaten by not only the frogs and other fish in her tank but also the other betas.
AND since they told me she was probably going to pass away I went ahead and adopted the other one as planned. Since I only had one heater I put them in a 5 gallon tank and split it with some filter thing (I hope it is safe).
This morning before class she was fine or at least swimming around but when I got back she had passed away. My second one looked a lot healthier than the first one obviously but I noticed some ichy stuff on her. So now I'm worried
I would like to say that I find it disrespectful to take pictures of those who have passed away but I am only doing so to help protect my new female and healthy male
