Picked up this little guy yesterday. During his first hour in the tank he was hiding and when he did show himself he was not yellow at all! Blackish/Gray spotted. Within the hour he was mostly yellow. Then, very quickly he seemed to want to explore the tank and by morning it's like he owns the place! I did a feeding about 3 hours after introducing him to the tank and he gobbled up the food! (Rod's food original) He is eating sheet algae and everything. He was also nibbling on the molt from my new Scarlet Skunk Shrimp.
