Crypts are rooted plants:I didn't think they had rhizomes. The crypts that come from the store potted and witht he roots wrapped in some sort of cottony material can be divided, so I imagine those pulled from the substrate can, too. You make experience a "melt" in reaction, however, but the leaves should come back if the roots are healthy.
well...i took a closer look and i'm not really sure i see a rhizome. i have a naturally planted tank...so the crypt is rooted into gravel over soil. If there is a rhizome it is in the gravel...i was wondering if i could do this without uprooting the entire plant.
I think if you do it while it's still planted and slice with a razor, you're going to damage a lot more leaves than if you lifted it out. Once lifted, rinse the roots so you can see where you want to divide it better. There's probably a zillion little crytps that make up that big clump. Divide just a little or divide a lot, your choice.
