When do you say enough?

[Aquattro]

Or do you, like me and others I know, need an intervention? I continue to acquire frags with absolutely nowhere to put them. I have about a dozen unique frags sitting in racks, and not a square inch of useable space to mount them. Most of them tabling too, so they need a fair bit of room.
How do you decide what needs to go in order to make room? No, bigger tank is not an option...

Who else does this??
