Yeah, I know I don't need one, and that purchasing a HOB will eventually be a waste, since the current plan is to sell one of my kidneys and my spleen to get a bigger house so we can have a larger tank in addition to the 4 we already have... *thud*
Seriously though...the reason you stated above, that the big tanks are more stable than the small ones, is the only reason I was thinking of getting a skimmer for the tank...I figure every edge I can give myself is a good thing.
