Looks fun! There are so many plants that would work in that setup. I just got the Foresta 60E last week and wrapped all the sponges with moss. Waiting on plant orders now.
So far I’ve been absolutely loving it! I’ve had the foresta 35E and it was one of the coolest additions I’ve ever made to my gallery! You should go to buceplant for your plants! They have insane selection and quality.
It sign that you have too much humidity. Keep the lid open on the front like 2cm wide. It should be enough to prevent mold and to keep the front glass clear of condensation.
