I have been using a 12 gallon nano (JBJ) as a place for softy frags. Been using it for 18 months. The hood just quit working again! This will be the third hood in 18 months! These things are junk! DO NOT BUY A JBJ NANO TANK! I think I'll just move everything to a twenty long and ditch the junky JBJ tank. Crap, I'm mad. Tried calling them, girl with such a heavy accent was speaking but couldn't understand a word. :x
