Well, I only have a couple members of the Onc families, but a couple of mine were bursting at the seams when I got them. They have new growths that squeeze in. The newer growths seem to sort of grow higher, so that they get the room they need. Sort of like stacking up bricks, one slightly off center from the ones below it. It hasn't seemed to hurt them, but it makes it !$%&@% hard to divide - I mean, where to divide, and how do you cut through that mass?? Any way. Wait and see, these seem to be pretty tough guys, if they can survive with me. LOL Maybe post a picture so we can get a good look.
