Well over the weekend My buddy gave me a 6 gal nano cube that was given to him. It has been set up for 3 months with sand and live rock. It was a little dirty so I did a cleaning and changed the pump as it was faulty but other than that cool little tank. We don't quite know what to stock it with. I think we will go fish only with some shimp. This could have disastrous results, meaning we probably will have 10 more salt tanks within 6 months the we go. Anyhow going to put a fish in today and see how it goes.
