Personally i think yes the tan is impressive and will make people go "WOW!!" and they have really gone for it with this so i congratulate them on that!! But, whats the point? non natural behaviour, must have some effect on the fish, doesn't not look natural, (looks sh*t in my opinion, i respect others opinions that they like it

) also the filtration is not that hard to do,
1. You just need lots of Biological Media for good bacterial population,
2. Lots of water volume far far greater than the tank itself,
3. Lots of money to pay for it all lol,
4. lots of time to do it
and
5. Have nothing better to do than ram a single tank with all those beautiful fish when they could have set up many tanks and had more natural looking and behaviouring fish.
Isn't that what we all strive for?, to make the animal as comfortable as possible and closest to its natural habitat?
and i am not surprised at why the fish are not aggresive to each other they probably don't know wear to start!!! same method as when introducing African Cichlids load it with lots of them and they will spread the aggression so you may not see much, also the same with Tangs too!!
those pics do look a bit fake, i.e. Drawings

some do look a lil photoshopped, so i can see the mistakes others have made, and whats to say that its all a hoax and was just set up for the single photo shoot
No offence was meant by this post
peace to all of ya and keep up the good stuff
