People on facebook were asking about xzina that grows in stalks and doesn't seem to take over a tank. I have this xzina and have had it for a number of years. Typically when it gets to big I just cut off the stalk and throw it away and let it regrow smaller.
Anyway, if you are interested in frag let me know. I don't have any cuttings at the moment but can easily make some. I can either sell it to you unattached or wait a week or two and have it attached. I am thinking $20 per frag?
