@sport_billy Charlie joined our family yesterday & is teeny tiny! And while normally I'd keep them apart for a bit, after their initial "sniff & greet", they CRIED for each other until I put them back together. (Charlie's little habitat is smack next to Gus's and they were literally nose to nose through the wire & crying for each other!) They are only together while I'm awake, present & supervising. Once it's nighttime, they will be in separate habitats till morning, just until Charlie is either a little bit bigger OR Gus learns that you don't attempt leap frog with your brother. Safe over sorry!
