Well, I bought a lovely crowntail betta two days ago and he now has ich, my levels are good, and my other fish are healthy and the tank has been set up for over two years. He was fine last night with no white spots or anything but this morning he had a white grain on his left pectoral fin and one on his tail. So my first thought was to turn up the temp, but I can't turn it up any higher! So I was thinking about salt, I have atlantic sea salt and I was wondering if that would be suitable? My corys are in another tank at the moment and I have no snails in there. Here's a picture of the betta before he got the ich, I was overjoyed when I had seen him but I was only in for plants.. I just couldn't resist.. P.S. My qt is busy with other ill newbies. Thanks in advance.
