anything hard to find or rarely imported/ collected, we are lucky enough in the GSAS to have members who travel the world collecting fish and plants,Cool! What are considered rare plants? Excuse my ignorance on the subject.
like nymphae minuta, its a mini lilly plant that flowers under water!
I picked up a breeding group of Cynolebias constanciae killies, ..they are endangered in the wild and are a CARES fish, our club really likes to breed endangered fish to keep them alive and well.
