Just wanted to say thanks to fluttermoth. Stanley's white spot disappeared by the following morning after doing a partial water change. He must have bumped into something. He's been in the tank for a year now, so you would have thought he knows his home, lol. And NickAu, lol, he's a handsome pet.
thank you for your reply. Sorry about the pics. Lol. Tried but Stanley kept moving too fast and the flash kept landing on him. I will change his water as suggested. Regards, Millie
