I get nano, but what makes it a picco tank? No fish?
Mrc8858 said:Pico tanks are usually 5 gallons and under.
Predfan27 said:+1 to that.
I believe when it comes to SW, Pico can refer to 10g and below. I've even seen 20g referred to as Pico. I generally draw the line as 10+ to 29 as nano and 10 and below as Pico.
It's funny to note the comparison to Fresh. Where 10 is pretty standard!
