It seems that most of the responses are near a year old. Is there anyway of taking them off and making room for new ones? I have some waving zinias that I need to get rid of. the boogers reproduct as fast as I can frag them. I have some Kenya trees as well and can separate with some cold coral if anyone is in need of any. BTW, these are for free, and if I misspelled anything just play like I spelled it right. Take care.
