My first reptile, crested gecko

Hey I'm completely new to geckos and I signed up here to make sure I'm doing things properly and to get help and advice if needed. I'm not entirley sure how old my gecko (Fluffy) is but he/she is too young to determine a definate sex, if it helps I'd say it is about 2-3 inches long (including tail). I have a few current issues I need help with but I'll find an appropriate section on the forums for that. Oh by the way My name is Kieran and I'm in the UK
