What lighting do you have on your Biocube? It's a 14, not a 29, right? Your nems look great! Our class is either going to turn our BC 14 into a Caribbean biotope or nem tank. They need something they can feed badly! Ugh - suddenly I wonder if I should go for another 29 tank and ditch the 14. 14 seems so tiny, but I have it with water and sand and some rock and it fits in the space easily. I hate making decisions.
