The BioCubes just came out and are somewhat difficult to get ahold of right now but I found one near me. They sell them in 8 gallons, 14 gallons, and 29 gallons. I have the 14 and love it, it's made very well and everything works great so far. They have PC lighting (mine has 48 watts) with each light on a seperate control (actinic and the other white one) and moonlights on a seperate control as well. The filtration goes through a filter pad then down a trickle filter of bio balls (I replaced with live rock rubble) and then is pumped back through the display. It's a nice tank and I would go with it over the JBJ just becuase I had one and it cracked on me for no reason at all. I saw the 29 when I bought mine and it was pretty cool looking, havent taken a look at the 8 yet though. The Finnex M tank is another nice looking nano and I heard the new one from Red Sea is supposed to be junk so I would stay away from that.
