Hi,
Another member with multiple tank syndrom! I have 1 75 gallon,1 29 gallon, and 1 10 gallon tank. I have given away a 29 to my nephew, and a 20 long to my daughters girlfriend, and another 29 to my other nephew. Hubby started having nightmares of living at the aquarium so I had to cut back. Of course His fish are in the 75 gallon tank. Hope to learn from you as well, as it would seem your 10 years of fishkeeping have been good.
