I am thinking to get a Panda Cory and i went to Petland last week and they were out of stock at that time, when asking them when they will get them, they said Tuesday which means today, so the panda Cory will be very new to the store, will it be ok to get it tomorrow? or should i wait until Friday? i mean since the store just got them and then i go and buy it, will they get stressed out? and die?
