So I was thinking about adding this guy to my 55 gallon tank, but I have a couple of questions. I read almost all the forums I could find on these but hoped someone would be able to help me on more specific questions. 1) Do I have enough lighting: Nova Extreme HO 2xT5 54watt lights on 460nm & the other daylight 10K. 2) Do I worry about it stinging me when I handle it? the LFS lady said I don't have to worry they don't sting, but I don't take anyone's word for it when they are in the retail business trying to sell me stuff. 3) At the LFS one was bleached really white and one had some purple to it. Any corelation between color and health? 4) Also, when she was showing them to me. One really clasped to her hand when she touched it. Like sticky glue and the other didn't stick to her hand at all. Does this have anything to do with health? 5) How can I tell if it's dead or dying? if I think of anymore i'll ask. sorry so many questions. i like to get as much info about something I am going to buy before i buy it.
