What are you planning to put in it? I keep a couple of 1.5 gallon picos for unusual hitchhickers and undesireables. I kept a pair of aptasia in one once just to see how many there would be - hundreds - if left unmolested and an unusually large - or so I thought at the time brissle worm. The current occupant of one of them is a stone crab (I think) that came with something I ordered (I have forgotten what now). It was really tiny when I found it but has now grown to quarter size. Unlike your good looking tank, I do not even attempt asthetics.
