LOL, it really IS obsessive! I started out with a small 10 gallon tank, then switched to a 30G, and now getting ready to set up a 75G! But that's not all ... in the future I want at least a 125G! I suppose it is the beauty of aquatic life that makes us all so fascinated with aquariums and that makes us want to get "just one more tank," lol. Plus, ever since I discovered how beautiful planted tanks can be, I've wanted nothing more than a large beautifully planted healthy tank. It is such a wonderful hobby

I am glad I got hooked!
P.S. There is nothing more relaxing after a long and tiresome day than coming home to gaze at a beautiful tank. It's indeed true that aquaria have calming effects on people.
