So I noticed that one of my guppies started to swim kind of weird last week, like they were coming down with the fish version of scoliosis. I didn't think too much of it because she didn't seem to be in distress and was still eating fine. Then earlier this week I noticed that she had some small white spots on her and her poop was pale and stringy. So I started to put some of the API anti-bacterial medicine in the water. So yesterday I looked and all but one of my guppies had the white specks on them and the first guppy wasn't eating anymore.
So I got up this morning to check on them and one of the females died in the night. So I took her out and did a 25-35% water change and added a little salt. I've slowly started to turn up the temperature and right now it is at 82 degrees. I separated one of the females that looked really bad and put them in an isolation tank and put some salt in it, I', pretty sure she is going to die. I also found the guppy that had this first dead after the water change. Is there anything else I can be doing, I don't have the money right now to go and buy ick medicine for them.
Also are there any precautions I need to be taking in handling the tank, for me and the fish. I am letting my stuff dry completely before using it in my other tank, as soon as I can I am going to buy stuff so I don't have to share between tanks. Thanks.
