I think my 4 month old crested gecko may be having some delayed growth or something. He/she is 4 months old, and only 8 grams, 5.5 inches long. He/she has never shed once in the 3 months I've had him/her. My leopard gecko is 2 months old, and has outgrown him/her already. Is this normal? Is he/she a normal weight?
