I've got my first 1.1 pair of cb U. Sikorae arriving on Tuesday. They are ~4 months old. I spent the last few weeks constructing a custom 24x24x36 vivarium to house them (hopefully expand it to a trio eventually). Just as I'm getting ready for them to arrive, I read that some folks think its best to house juvies separately in much smaller enclosures, ~10g or so.

Anyone have experience raising juvie U. Sikorae in a large vivarium together vs small vivariums separately?

I did something like this, and I wish I had raised them separately. They didn't gain as much weight, or so it seems. The girls might have been bred prematurely.

I think it's a no brainer to house them separately. You can monitor their feeding, pooping and health better. If they're together, you don't know if one is eating 75% of the food, and you have no idea who's pooping or not.

There's really no reason to house them together, IMO unless they're paired for breeding, especially since sikorae are so small and these guys are juvies. They won't take up much room.

I have 2 young juvies that I do house in separate 10g. This was recommended to me as the males do mature quicker than females and will attempt to breed with her when she is not mature enough for breeding.

100% of the time...it is most beneficial for both animals if they are raised separately, regardless of species. If they are raised together, there is a chance that one of the individuals will grow faster than it would have if it was housed individually due to hormones and extra food...but the other will get the short end of the stick.
Lets say that if they were housed individually, you would feed each gecko three appropriately sized feeders a night. If they were together, and you put six feeders in...one gecko would most likely get the majority of the feeders. If they were housed together and you put 10 feeders in, the more aggressive gecko will feed more freely, but the more timid one will usually not. This is much more evident in Phelsuma than Uroplatus but it still occurs.
In my experience, baby and juvenile Uroplatus have two significant growth spurts. One starting at the end of their first month (after they have mastered the whole feeding thing), and then to reach the final 1/3 of their adult size/length. It is imperative to meet their supplement needs during these growth spurts...Calcium, Calcium, and Calcium.
