Pik, the phal is still a baby, so it's def. not going to be its home forever
The container is a hexagon (I think, its got 5 sides) and is about 11in tall, 16in across and 9in deep (those are at the widest parts)
Ellen, I put it in the small container because everyone on here always recommends the spag and bag method after root rot, and I don't have plastic bags usually just laying around, so I used a container. This is the first time I've had an issue with root rot, so I went by what others have said. The phal is mounted and by an opening in the terrarium (which will also have a fan in it as soon as I'm able to get one)
