I agree with Kien, I've had a 2 previous boxfish and both develped ich to the point of no return no matter what I tried. Once was a yellow spotted boxfixh and the other was a smaller one which I can't recall the name. I was impatient when intoducing them which I suppose we all were when we started in the hobby. Now that my 50g has cycled I have another small (at least right now) yellow boxfish which does quite well. He is in a fish only tank with very calm tank mates. I replaced my powerheads with smaller units for less flow and he is out in the front of the tank all the time, unless he is in the back looking for food. I've been looking at the spotted boxfish species you have the links to above there and when the time comes to re-home the yellow I will definitely look into it. I would be interested if anyone else has had experience with the spotted boxfish besides Kien.

As far as them poisoning your tank, I am always looking at my different set ups throughout the day when I'm home. So the chances of something going wrong to point of no return, I would say the chances are slim. There is probably a better chance of power outtage!
