Hi,
Did the breeder say what he thought the morph was?
Congrats on quarantining him though as it gives you a great opportunity to observe him.
I normally remove them from the bag/ tub they were sent in and let them get used to their new enclosure.
I reccomend not handling new arrivals until they have three consecutive meals for you - don't be surprised if it takes them a few weeks to eat in a new environment.
