I'm telling you, for sheer entertainment value, the nano-reef is hard to beat. I know you might find it hard to believe, since there's not even any fish in there, but there's always something going on.
It's a little stressful, too, of course. After having to float ice every few hours to keep the temperature down low enough not to kill the coral and snails, I finally bought a chiller. But before I could even figure out how to install it (which, sounds like it should be easy, but isn't), suddenly it became winter and I had to install the heater to keep the water warm enough not to kill the coral and snails. The only reason that I don't have the central heating on in the house right now is because less than a week ago I had the A/C on, and I'm too stubborn to switch from one to the other without at least a month in between.
Then there was the night that I realized there were hundreds of tiny little bugs crawling all over the rocks. I've learned to love these copepods because they're a sign of a healthy tank, but for the first few minutes my skin was crawling.
And then yesterday, after what, two or three months of the rocks being in the tank, I saw long tentacles coming from a hole in the rock, going around the corner and grabbing at things. Holy crap. The tentacles have to be at least four inches long. They're really skinny and translucent, but still, how did I miss seeing this for months? True, they all sucked back into the rock when I changed the lighting, but still.
I think the aliens have arrived...
