In the guys' defence tho mabey he is on to something. Just because we all keep our tanks a little higher doesnt mean its better. Heck just because nature does it sometimes doesnt mean its best, only acceptable. We all live in temperatures from -40 to +100, but which is best? Perhaps a slightly lower temperature will increase longevity and color at the expense of growth or whatever. Imagine where this hobby would be if no-one ever thought "outside the box" Man, i can just imagine the hoopla on RC when the guy who first suggested putting 6 inches of sand on the bottom of a reef tank, or too take out all the filters and just run a bubbly tube thinggy and throw out the foam every couple of days???? These people were thought mad in thier day.
As for never feeding his tank.....well he certainly isnt raising tangs or anthias but what about mandarins, lawnmower blennies, CBB's ? they would all get along fine without feedings.
Food for thought.

The problem with that theory is if corals could thrive in lower temps then they would grow further north. California is not exactly known for its coral reefs

If he had the last few fish PoonTang mentioned the it wouldn't be a big deal as long as he made sure there was pods available for them to eat. However since he's waiting to see the tang's spine before feeding, I have an issue with that.

As I said before, the nutrients to grow the algae, to feed the pods, to feed the fish --- has to be coming from somewhere. Is there enough breakdown from LR erosion to do that for 8 years?

Disagree that even mandarins, CBB's, and lawnmower blennies are fine without feeding. It's true that some will not be trained onto offered foods but that doesn't mean they don't do better, live longer and healthier lives, if they do get trained onto offered foods.

And Marie is right. As I mentioned in another thread, even Hawaii, which is in the tropics, being on the northern edge of the tropics has waters that are considered too cool for a lot of reef formation. There is reef, but it's not comparable to the reefs further south.

Not saying 75 isn't acceptable. It's perfectly acceptable ... but debating 75 vs 79 is like splitting hairs IMO. :)
