Besides more spacing be tween shelves, I was hoping to eliminate the two verticle supports in the front to allow for more flexibility in tank selection. But I worry that the weight would cause the shelf to sag. >>>8 Will the top shelf be too warm for worm cultures (my guess is yes)? Dunno. I leave this for someone else to handle.<< FYI - One of the killie guys, Richard Sexton, wrote "Depends on the kind of worms: white worms like 60-65, grindals like it 70-80."
