I've repotted the Bl Yellow Bird in a leca/bark mix (heavier on the leca) in a clear pot with an air cone/side ventilation. It's a bit over potted but the bottom of the pot up to the top of the air cone is covered in straight Leca to help with drainage. Right now I have it on a seedling mat to help stimulate root growth since we've had a significant drop in temperatures today and freeze warning for tonight.
