Didn't plan on adding anything else till the 50, and I could understand it sounding overstocked, though I see a LOT more stuff in other nanos of the same size. Everything I've got is small, and I'm aware of the full size each things achieves in the longrun, how fast/slow they grow, but I also know that most of the stuff is moving into the 50 gallon or a nano-cube in the near future. So, temporarily contained in the 10, it doesnt seem so bad. And as far as my sebae, all I've seen it do is stay on its own end of the tank, keeping away from everything else. Now it sits behind my liverock, instead of out in the open directly under the light. In this spot, it does get light, and its fully spread open, rather than retracted, and its bright as well, rather than dull or limp. Should it be more aggressive than what I'm describing?
