Reefkeeping... not exact tho, No rotting 55 gal drums of pcb's or spent tire, or beer can tabs...not very realistic are they?
Unfortunately you're right. Some places in the world still have relatively unpolluted reefs like Indonesia and remote parts of the Great Barrier Reef. However, I've been diving in Belize and Florida and you do see trash :(
That's a shame, it doesn't help that global temperatures are causing coral bleaching also.
Wow, very beautiful. 
Niiiice!
DH's hobby, I prefer snorkelling at the blue lagoon here in Cyprus. Nice tanks.

I was in the hobby for a couple of years and it can be one of the most expensive and addicting things you'll ever come across.
