I mostly do Java Moss, Java Fern, Tall Val, various Anubus, and am trying to do Crypts, with moderate luck. Basically whatever my fish won't kill / destroy. I like to have heavily planted tanks though and would love some more growth from everyone and more to sell at the auctions. I know the cost is sorta crazy, but as fixtures break, I figure why not at least try out a LED fixture on a tank or two to see how it goes... plus it would be nice not to be the number one energy user in my neighborhood (thanks DTE for bringing that to my attention).
