lighting really doesnt matter at all other than to keep plants alive in thier tank they deffinatly do better with plants. You could do a mess of java moss and java fern with simple grow lights from walmart for less than $10 add a sponge filter and thats it. heres a really good guy for shrimp stuff and plant stuff on ebay, sightly slow on shipping (malaysia) but it all shows up great and cheap. http://cgi.ebay.com/Mineral-Rock-Cherry-Crystal-Red-Shrimp-Color-Enhancer_W0QQitemZ250305180951QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item250305180951&_trksid=p3286.c0.m14&_trkparms=72%3A1205|66%3A2|65%3A12|39%3A1|240%3A1318|301%3A1|293%3A1|294%3A50
