Swords are really heavy feeders and I had to really dose my 29g a lot to keep up with them. Once I moved most of them out, the rest of my plants really took off.
You'll forget the java ferns are there, they grow so slowly. Mine has put off 2 new tiny leaves in the past 3 months so don't worry.
The crypts will die off when you move them but should bounce back pretty quickly.
Just stay patient
