Good points Cortnee!!
I guess a better comparison would be to have the small closet as my 18 month old's play room. Then let her have the bedroom to play in when she gets older.
You can not see it because you are a responsible fish keeper, I wish more were like you. I used to work in a LFS many many moons ago. I've heard and seen the horror stories. Fish keepers like yourself are rare when you sample all of the fish keepers in the country. Shoot, 1% may even be too high of a number. Now if you were to sample the members of just MFK the number would be a lot higher than 1%, just signing up to a website dedicated to the hobby shows you are more responsible than the average fish keeper.
Unless I know your situation first hand I am 100% against "grow out" tanks. Just my opinion from my experience working in a pet store.
You know what they say, "Opinions and butt holes, everybody has one". :lol:
