Our first mini tank crash : /

We're going through our first tank crash with our 6 month old 90 gallon tank. In the last week we've lost a torch coral, a favia frag, and possibly a royal gramma. One of the clownfish looks like it's sick and the BTA doesn't look great and the condy anemone is on the move for the first time in months. Joy.

Some of these things actually aren't related, they just decided to happen in the same week to kick us while we're down. The favia frag fell into a torch coral at some point in the night and didn't recover, it died within 24 hours. The torch coral that is in the process of dying is a new one I picked up a week ago. Looked great for the first few days and then went downhill fast. Most of it's exoskeleton is showing and I expect it to be completely gone in the next 24 hours. No idea what caused it, the other torch coral is doing great. We've had that one for 2 months or so. I did put them close to each other, not touching but close. I thought that torch corals were supposed to be okay next to each other though?

I noticed the royal gramma looking off a week ago. It's skin looked sort of cloudy and like it had a lumpy mucous film over it. At first I thought it was because my boyfriend had cleaned the sand and something had irritated it's skin because there was a lot of sand debris floating around. But it didn't clear up after a day and I noticed the royal gramma rubbing itself on rocks and on the sand, which seemed to only make things worse. Unfortunately the little bugger is fast and likes to hide in the rocks and we haven't been able to catch it. I saw it once yesterday for about 10 seconds and then it went back in hiding, haven't seen it at all today.

Today we noticed that one of the clownfish seems off. Usually it's a super aggressive feeder but showed no interest today It doesn't look like the royal gramma did, it's skin doesn't look bumpy or cloudy. But it seems like it's lost some of it's color around it's fins. I did manage to catch it and we have it in a hospital tank within the display tank, setting up a quarantine tank now to put it in. The only other fish in the tank are a purple tang and another clownfish. Both of them look fine but I'll probably catch the other clownfish and put it with the other one in quarantine. We're debating about the purple tang. The quarantine tank is a 20 gallon and we're concerned about stressing out the tang by catching it and then putting it in a smaller tank. Still not sure what the fish have, it doesn't look like ich. Maybe Brooklynella? The purple tang is the last fish we got which was about 6 weeks ago. We didn't quarantine it but it was at the LFS for 6 weeks by itself in a tank. The clownfish and royal gramma we got about 4 months ago. They've never had any health issues.

Because it's a fairly new tank we check the water parameters every couple days, and aside from having to dose daily to keep alkalinity up everything has been stable.

Ammonia: 0
Nitrites: 0
Nitrates: Less than 5
Phosphates: 0
Copper: 0
Calcium: 410
Alkalinity: 9.3
Magnesium: 1400
Salinity: 1.025
PH: 8.08
Temp: 79.4

The good, yet frustrating, part of this is most of the stuff in the tank actually looks awesome. We don't have a lot of fish but we do have quite a few coral frags consisting of, zoas, hammer coral, torch coral, favias, octospawn, dendro, goniopora. They're all doing pretty good, most of the have grown quite a bit since they've been in the tank. The condy anemone still looks awesome although it's on the move so I'm guessing something is bothering it. I picked up the BTA about a month or so ago, it looked good for about 2 weeks and then started acting weird. Lost some of it's color, would hide at various points throughout the day, etc. It never moved from it's spot though. I actually thought it was going to split but it hasn't done it yet and it actually looks better today than it has in weeks. It did poop yesterday so maybe that's what it needed to make itself feel happy again.

If anyone has any suggestions for what could be causing some of the problems in our tank that would be appreciated. Our plan right now is to quarantine the sick clownfish, if I can catch the other one I'll probably quarantine that one too. I think we're going to leave the tang in the display tank for now. I haven't seen the royal gramma yet today so unless we take apart the tank I don't have anyway to catch that fish. I'm keeping an eye on the ammonia levels although if it does die within the rock between the starfish, emerald crabs, and hermit crabs I think they'll eat it pretty fast.
 
From how you're describing the royal gramma, it kind of sounds like brooklynella. I would remove all the fish in case it is and be ready to treat.

There are a few meds that can take care of brook: formalin, metroplex, acriflavine(ruby reef rally)

I would look into getting one of these meds, preferably metroplex. Only treat in a hospital tank and all fish will need treated. The tank will also have to go fallow for 6 weeks for brook.

Posting a picture of the gramma would definitely help too.
 
As for your frags, I think they more or less killed one another. They both have powerful stings. Just make sure frags are secure from now on.
 
I managed to find Kordon Rid Ich Plus which appears to be a mix of formalin and malachite green. I also picked up a bottle of Pro Aquatics Malachite Green. Doing some research now on what would be better to treat with, I'm guessing the Kordon stuff. Only the sick clownfish is in qt currently, I couldn't catch the other one which so far looks healthy. I haven't seen the royal gramma at all today. Is it possible the royal gramma and clownfish are showing signs of chemical warfare? We did a water change yesterday, 20%, ad a small 10% change today. We're planning on doing another small water change tomorrow and looking into running carbon.
 
As for your frags, I think they more or less killed one another. They both have powerful stings. Just make sure frags are secure from now on.

We bought some epoxy to secure the frags but it obviously didn't work that well. Going to try super glue next time.
 
I would use the kordon rid ich because it contains formalin. Epoxy works but super glue seems to work much better.
