@Arachnophoric looks like the seller lied to me? I don't mind keeping a sling especially a fast growing a. genic but mine looks nothing like yours yet. Not cool on his part either because i'm a beginner and can't really tell.
Upon further inspection the abdomen is very pale so i think it's far from a molt actually. I think the breeder just fed it well and i'm dealing with a very early juvenile. Will post a pic of it's molt to make sure of the gender when it happens tho
