So the other day my gf brings Goliath with her to work..which is at a PETCO. Well one of the other girls that work there just happens to bring in her female yellow too. My gf asked how old she was and the girl said she 4 years old. I didn't get to see the yellow but my gf says it was maybe a foot longer than ours and barely bigger in weight...Goliath is only 8months old.

So either her yellow is a runt...she has no clue how old it is or she's just not taking care of it like she should
