I did this as a 192 piece classic cut - it got tougher after a little while - the blue background was the easiest for me - then everything else got tougher. Is this from an actual reef or is it from an aquarium? The reason why I ask is the fairly uniform blue, the appearance of what looks to be a very flat bottom, and, what appears to be largely goldfish.
This was fun to do...very interesting coral reef!
Thanks Staff for all the great puzzles!
