Help Me, Please
I think my guppy fish, Cockatiel, has fin rot. He had a perfectly round tail when I got him about a month ago. Now his tail looks like something took a bite out of it. I haven't gotten new fish yet, so I'm wondering if it's possible that the stress of being alone caused it? I have a plan- but I wanted to get some input on the steps I plan to take.
1. Move his tank to a sturdier location (it's on top of my dresser and wobbles a little bit when I get into it, I think it may stress him out)
2. Check the water (My local pet store will check it for me if I bring in a sample)
3. Get medicine for him and dose it properly
4. Get tankmates as soon as I know everything is healthy.
Any advice on anything else on what else I should do?
I'm so worried.
