hi ive had my african dwarf frog for about a week and a bit hes settling into the tank ok i had a few problems with feeding (for those of you who read my other therad ) but hes eating fine now i notied about 4 or 5 days ago it looks like it had loose skin around the neck and start of his back but i didnt say anything about it but ive just seen him again now and it looks like he has loose skin and the bottom of his back leading to his legs and the skin around the neck and start of his back area is a clearer darker greeny brown my questions are - do african dwarf frogs shed there skin? has mine been doing it? how often do they do it? and how long does it last? thanks
