It might be that the ones I bought were infected with something at the farm? For the ones I tried propagating, perhaps I cut them with scissors that weren't sharp enough. Their rhizomes can get quite thick.Thank you - hmm, sounds like a particularly sensitive species...? It's a shame as I really love the look of it. I'm glad you've got some that is working for your tank. I'll probably give it a try and see what happens.
Sharing couple of pictures! So weird that these aren't Corydoras anymore
