Both tanks seem fine to me - if they are fine for you.
If you want my opinion, I would consider returning the 2 green chromis, and then moving the pair of maroon clowns over to the larger tank.
You'd have less fish load on your reef tank, which may make it easier to maintain the water quality for your corals.
The maroons may enjoy having larger tank to live in.
But again this is just an opinion.
Sound like nice tanks - got any pics ?
