So I got a gargoyle gecko yesterday who I have named Astrid. fired up she is like coconut color with some blotches of a rust color, fired down she is like a sandy color with rust colored blotches she is 4-5 years old. When I got her in the terrarium I noticed that she had a scale discoloration at the tip it was like a light gray color but I thought maybe she lost her tail and that's how it regrew. Well, this morning I look in the terrarium and her tail was like 95% covered n the gray color, is this shedding? If it is what can I do for her so she has a good shed?
