I have a small group of spotted's and one of the juveniles has picked up a fungus. The toes seem to swell up and the area is grey. Onlu one turtle is affected. They are kept in a 65 gallon tub with a Pondmaster 190 and several bricks to bask on. I do regular water changes and the water is kept at 4 inches in depth. I remember reading a post about using acriflavin and if anyone has an idea or more info please post or send an e-mail. Thanks to all and keep up the good work.
