They look great to me
If you have a lid, I suggest filling it up all the way, but other than that I don't see any issues, and since they're 5G tanks, they still have enough space even when not filled. What temperature do you have them set to?
As long as you've conditioned the water and it's at the right temp, I would say you could start acclimating them right away
