I am glad I found your thread. I saw those in the LFS the other day, and almost bought one. I was not sure if it would be worth it. I will for sure be tagging along for the ride. As far as the parent thing goes, I am 26 and my Fiancee is 23, and we live with her parents. It is so she can go to school and to help them out. They get a little nervous every time I mention another tank. But it is ok. They said no pets, and now we have 2 cats, 2 leopard geckos, 2 corn snakes, and 5 fish tanks, soon to be 6. They keep saying no more animals, but we just get anyway. All of ours save for the cats, stay in our room. The way I got around the scare of the new tank thing, I started paying the electric bill for them. Now when I say new tank, they just kind of look at me, and let it go. You could try that tack with your mom if it comes down to it. The paying the bill part, not the just bringing more in part. Best of luck, and I am looking forward to where this tank ends up.
