I have 4 right now(1 maxima, 1 crocea, 1 derasa, 1 Hippopus). Right now I'm on the quest for a blue squamosa, blue derasa, or small gigas. I'm starting to battle wether or not I should keep my LTA. It is well over 12", has spawning percs that reside in it, and I've had it for almost 3 years. I've grown pretty attached to it but now I've got the clam bug. The LTA is in a nice lagoon area of my tank and if it goes I will have lots of room for new clams. Hmm.....
