I have a 20 gallon tank and my xenia is determined to take over most of it. I have a 10 and a 20 gallon tank, and I was thinking about setting one up to put the xenia in. I have already sold some to a LFS for 25 bucks store credit. I am planning on trying to sell or trade this xenia. I don't want to put to much money into this tank. I was just wondering on how I should set it up as far lighting, water flow. I plan on getting a few small peices of LR and position them next to the establish xenia covered rocks. I also plan on adding some mushrooms as they are multiplying like crazy as well. Well enough rambling on now, anything anyone can say to help would be great. Is this a good idea or not?
