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.
