After not knowing what a captain america was, and wondering for a while why its named that way when it looks nothing to do with anything captain america and then seeing the price...
I salute your cajones for stuffing that little tank full of pricey goodness. I really like the background you made the best though, lol. I saw another person setting up a big tank and he's doing something similar with the background. I've been wanting to find out what they look like after a year or two though, will it be completely coralline encrusted or resemble rockwork still?
Best of luck with that clam, hopefully he'll outgrow the baby tank soon!
