[tsubaki]

I thought because of availability it would be a drop in, but nooooo.
Daddy , the whole time saying, "snatch both of them out and put a surface tank on the floor". I'd prefer to have the floor uncluttered, at least this way I gained a little room near the rodholder and didn't sacrifice but 2 gallons in doing so.
