Ok I have a 9 gallon biube tank that's still in the box. I haven't found a place to put it yet and not really sure what I want to put in it. I was thinking last night of maybe setting up a small salt water tank. Now I know I probably won't be able to keep fish in it since it's a cylinder tank. But I was thinking of just putting some sand, live rock and maybe a few invertibrates. I was thinking of small hermit crabs, some shrimp, and snails. Would this work? I'd love to have a fish in there as well but I honestly can't think of fish that would be happy and healthy in a cylinder tank. If you can recommend a small fish to keep in it that would be great. But I'll be happy with an invertibrate tank as well. Maybe you guys can recommend some interesting looking shrimps or other invertibrates. I'm going to be doing some research on it. I'd definately love to have a small slatwater tank, since I don't have the room or money for a larger tank. So any info would be appreciated.
