I so wanted to pick up the last 40 breeder in town for my sump, but decided at the last minute that it just wouldn't fit with everything else I've got planned. So I'm now back to trying to decide between a 29g and 20L.
Still, $1 per gallon is a great deal, especially the bigger you go. They told me that the 33's came with the glass lid and light strip, but that all the others were tank only deals.
