WTF is going on with my tank?!?!

Last week I lost a large milli colony to what seemed like STN, yesterday I noticed the flesh on my bonsais missing from the tips. And today a couple 1" sections of my neon green birdsnest are bare (not just the polyps, but into the skeleton).

So I sat down at the bar and watched my tank for an hour.

Hippo Tang = eating birdsnest, taking chunks out of the skeleton and all.
Yellow Tang = nipping polyps on my softies
Chromis = nipping at bonsai and millis

Aren't these all "reef safe"? I have had them all for 6 months+ and this is the first time they decided to wipe out my SPS. Advice? Am I not feeding enough?

I opened the thread cause with the title I thought it was going to be about wickedfish. Usually fish will munch on the flesh if it is rtn or even stn already and dying

Sorry to hear Stephen...

Question: Why do you guys feed brine? I've always heard that it has little to no nutritional value kind of like eating potato chips and candy... tastes real good but not good for you. I've read that it's a really yummy treat for them and it's a good thing to use to get a finicky fish to start eating and then mix mysis and then just mysis after a while.

Mysis is actually worse than gutloaded brine on the nutritional value scale. :) My fish look at pellets like "what the heck is that crap sinking to the bottom of the tank" and then the inverts get it. I don't like anything hitting the bottom of my tank, and feel that is part of the reason my params are always inline... I dunno...

It does sound like they're just hungry and you're not feeding enough. So many people were telling me that fish don't need to eat as much as I was giving them a few months back so I cut my feeding down and I saw everything suffer for it. Increased the feeding a lot lately and everything is happy again.

You have a lot of fish. I have 16 and I was feeding about what you have been. Bump up the feedings and I bet everything will do better.

The fish are not eating your corals, they are feeding on the micro algae that forms on all surfaces of your aquarium (incl. liverock, glass/acrylic, etc.)
Start feeding them a half sheet (or so) of Nory on a daily basis and I can almost gaurantee they'll leave your corals alone

I agree with lurking that the corals must have been RTN/STNing already and then they start to nip at it. I have had that happen numerous times where my tangs would nip my corals that are turning for the worst.

Where are you getting this information? Can you post some links that back this up? I don't have time right now but I'll try and find some later to back up my theory...
Go start your own nutrition thread and GTFO of my coral eating fish from hell thread!! :D

Oh no, I guarantee you that they are indeed eating my coral, including big chunks out of the CaCO3. (now that still might because of micro algae, but they are still eating it). Going to start doing Nori every day rather than every-other and see if that helps.

Oh STHU! Lol I'm not trying to be a b**** and question your knowledge... I'm seriously wondering why you think that and where you are getting your information because it just goes against everything I've always heard and read... maybe I'm wrong but if I am I would like to know. Are you afraid that I may have just proved you wrong and you don't like looking stupid? ;)

Well if they've gotten a taste for blood now they may be coral eaters forever :/

Your coral is STN/RTN and ur fish are eating the dead tissue. What are the odds that all those reef safe fish just out of the blue decided to start munching SPS. I've seen my tangs nip at dead tissue before. That seems more likely.
