MY betta has fin rot part of his fins look shreaded. I was using him to cycle my 10 gallon with 3 other zebra daions and I noticed he seemed to be getting worse,so I put him back in his 1.5 gallon tank. He's swiming around nicly,but he seems to be happier in there than he was in cycling tank. I can't go to petco until friday,what can I do.
I als have coarse sea salt.
