This is just in the planning stages now, but my next project will likely be a nano reef tank. I'm thinking a 5 gal hex should do it for me. I think it would look sweet next to my bed. The goal here will be to do it cheap, and with the least amount of equipment necessary. Because of the size, I don't think any fish will work. I would like to do maybe one or two very small fish if I can, but if not, an invert and coral tank would be sweet too. So, what gear do I need and what stock should I get. I would like to filter only with live rock if possible.
