Lovely tank.
But I think the angel should go. Those neons will later become a midnight snack. Also they need to be in a tank around 30 gallons.
And glass catfish need to be in groups of 6+ or they won't do so well.
But overall that's a nice tank.
Before I stocked my tank I did some research and after mixed reviews with angels and neons I decided to give it a bash since then I have always kept angels with neons and never ever had any problems. Thanks for the other comments.
Its a really lovely tank. I kept a pair of Altum Angels which are bigger than the regular ones with neons for some years the Altums had mouths big enough to swallow the neons but they never did. You never know of course.
Nice pics
