I bought some from Gold's Aquarium in Calgary for $5/each. Not sure where you're located though. But I think I probably bought the last ones here lol

the gsp's kinda spread out over their discs, but they haven't opened. i was told they're fussy and that they can take a few days to open. so i'm not worried :) and i'm totally in love with my blue xenia :D

OK...what is officially considered a PICO and where does it become a NANO?? Might be a silly question but I am a bit baffled..:biggrin:

I think pico is less than 1 gallon and nano is less than 10 gallons.

what I read is that the true definition of "pico" is supposed to be under 2 gallons. nano's are under 10 and then you have "normal" tanks I guess? 1 site says my tank is available in 1 or 2 gallons, another says they're strictly 1.66 gallons. is any case i'd call mine a pico :p

perfect! thanks for clarifying...I had thought that PICO was under 1g and Nano under 10g but you just never know....:biggrin:

ive had afew picos and top off can be hard i think you should definatley put a piece of acrilic or hard plastic on top to help, if your useing a HOB filter try and put something in it to help with nitrates ect like seagel, phosgard or chemi pure they work good but i gess if your going weekly WC and dont whant any fish(but realy whats a tank without them:biggrin: )you dont realy need it, also be carefull of heat! i had a 1g pico i started last winter but took down in the sumer because the water would get to 86 with the light on!
