And Viktor, please make note of the two quoted posts above. This is something that you just recently asked me about in another discussion. Not that I think that it will be in our life time (but it could be?), but when they come, asOgertron3000 put it, "if aquariums become targets it will be videos of giant fish in small tanks with HITH they will be showing." You know, like a 12"+ oscar in a 55 gallon.
So while you are advocating the allowing of those types of set ups, to children or otherwise, please keep in mind that in the background people of your mindset will also be assisting the building of a PETA foothold in to our hobby.
Imagine if the anti hobby brigade got their wish and lobbied for strict laws telling the would be fish keeper what size fish could lawfully be kept in what sized tank. I'd love to be a fly on the wall when they all get their heads together and start drawing up guidelines. They'll end up right where we are now, arguing over what size tank is suitable, for life, for whatever type fish!!! The irony in that.
That's of course if they don't lobby to ban the hobby altogether and instead try and reach some middle ground.
