Hi Kathy, Great growing, your plants look very happy and healthy!
With my bad eyesight I can't tell for certain but all of those empty pots in your photo look a bit large for your AV plants to me. I'd try to find something shallower than those pictured or just a little bit larger than what your lovely plants are already potted in. You might like to post this to the Gesneriad Forum:
