It all depends on the coral, I had a pagoda cup die while all other coral was happy, if I dropped the temp the pagoda was happy but everything else looked like death. I let the pagoda cup either adjust or die, the needs of the many outweigh the needs of the few or the one.
It comes down to homework. Look for all the info you can find on a coral before adding it to your tank, it will save you lots of money.
74 is way too low for a reef, between 78 to 84 is best.

How about temp swings? say from 76 to 78 and back down? that hurt things much?
IMO...Not if it is over time
for example...when I get up in the a.m....tank may be at 78...lights come on...by dinner time tank is 80
so the temp swing is very gradual

There are times when a coral is hungry or stressed they fan out just before retreating , they send out poison darts at this stage to eliminate any opposition. Sometimes sudden stresses in water can make them withdraw right away. So being all fanned out does not always mean they are happy.

I know plently of Bandit angel owners and other high dollar angelfish owners who have them in full reef systems, where the temp never climbs over 74°F.
The temp itself isn't an issue. A quick change in temp will affect things. In preparation for a pair of Multicolor angels, my 90gal reef is currently 72°F.
I've said this before and I'll say it again, the temperature of your tank should depend on the fish you keep, not the corals.

poison darts? Ninja corals? how much for a small colony of those?

Corals have poison they give off to kill any opposition, running carbon keeps it down. My book calls it poison darts so I used the same language.
I keep my tank at 82/84 because my Hippo tang is happiest at that temp. Even new fish seem to adapt quickly and are very happy at this temp.
The only coral that seems to really need a lower temp was the pagoda cup. Everything else is quite healthy. I have over 15 different types of coral, a few I have had for many years. I gave most away when I got divorced two years ago, and have been rebuilding my reef for the last little over a year.

hey flower just curious what book are you reading?
when corals send out defensive slime it is easily seen.my are not they are just blown up to receive maximum light and nutrients from the water.

google nematocyst this is the "dart" that flower is speaking of many corals and jellies use them as a defensive and offensice weapon as well as for capturing prey.

Generally no, they usually can't penetrate the thicker parts of your skin on your hands. I know if my frogspawn brushes on the inside of my forearm, I get a few bumps.
Of course there are a few "perfect storm stories." There was an open cut on your hand and the coral got a ton in there. Your allergic to the venom, you were playing with a bunch of zoas and immediately stuck your fingers in your eye, etc...
