Up to you, in my orange one started out with many but most died off pretty quickly after popping up, as they get larger this may happen to yours, most plate skeleton farms I have seen only have a few large ones growing on them, never the ton o' babies. I kind of like the frag idea, maybe give them an extra chance to all make it? On the downside don't know if the fragged pieces with continue to make babies but you'd have a ton either way. Nano red plates for everyone!
