Thanks Exodus for the time you took to write that. I struggled with going with the smaller tank, as I have read how much more difficult it is to start out on a tank that small (although it is the larger biocube that I bought yesterday). In the end, I wanted to start out with a tank that was a bit easier to water change and I also wanted a smaller amount of sealife so when I do mess up, the tolls will be smaller. Perhaps a mistake, but I am still excited. If it goes well, I have a feeling the biocube will be short lived for me. Thanks Brian (pdxmonkeyboy) for helping me out!
