Fish Dying off, no clue why

Update... The Cardinal is on his last breath or two.
Dang! Sorry.
I had fish pass some months ago. I did put them on a plate and used a jewelers loupe to inspect the damage and gills. I sent the pics to Mr Fenner @ wet web.
In that case though. It was a murder crab.
 
All of my Corals and Shrimp are perfect except for my Anemones which are closed up right now.

I hope that Crab is doing hard time somewhere!
 
When I purchased my 120 lbs of real reef rock it came live. No cycle in my tank as a result. At the store, it's shipped to us wet and we keep it in a saltwater vat to keep it live. My concern was that if the bacteria all died, then there wasn't anything to help with ammonia with all those fish in the tank.
Thank you.
 
If you can catch the cardinal, why not go ahead and give him a FW dip using RODI (see below)? Sounds like you don't have much to lose by trying. Even if flukes don't show, if his condition improves following the FW dip it suggests you cleared parasites out of his gills. That would give you something to go on.

Also, have you used any chemical treatment on the cyano?

Freshwater Dip: Provides temporary relief for Brooklynella, Flukes, Marine Velvet disease (Amyloodinium); possibly even Ich & Uronema marinum (both unproven). Can be used to confirm the presence of Flukes.

How To Treat - Fill a bucket with RODI water, and use a heater to match the temperature to the water the fish is coming from. Aerate the water heavily for at least 30 minutes prior to doing the dip, then discontinue aeration while performing the dip. Fish aren’t overly pH sensitive for short durations like this, but you can squirt a little tank water into the dip just before the fish goes in to help bring it up.

Place the fish in the freshwater (FW) dip and observe closely. It is not unusual for them to freak out a little at first. Also, tangs are notorious for “playing dead” during a FW dip. The important thing is to watch their gills; they should be breathing heavily at all times during the dip. If breathing slows, it’s time to exit the dip. Dip the fish for no longer than 5 minutes. Multiple dips may be done, but it’s important to give your fish a day to recuperate in-between dips.

For flukes, use a dark (preferably black) bucket so you can see if tiny white worms fall out of the fish (especially out of the gills) at around the 3-4 minute mark. The worms will settle to the bottom, so you can use a flashlight to look for them there as well.

Pros - Provides temporary relief for a wide range of diseases in a chemical free environment. Can “buy you more time” until a proper treatment can be done.

Cons/Side Effects - Not a permanent “fix” for any disease, as FW dips are not potent enough to eradicate all of the parasites/worms afflicting the fish. Some fish can have an adverse reaction to a FW dip by appearing unable to maintain their equilibrium once returned to the aquarium. If this happens, hold the fish upright (using latex, nitrile or rubber gloves), and gently glide him through the water (to get saltwater flowing through the gills again). It is also a good idea to place the fish in an acclimation box until he appears “normal”.

I can't get a net in to where he's laying. If I try to grab him with tongs it might spook him if he has anything left and end up where I can't get him when he dies. I think he may be too far gone for the dip but its a great idea if I can get him.
 
Did you do the necropsy on these guys? Were the gills held open and pale or bright red? How are you getting air into the tank? Could be low oxygen. Nems closed up could be something too. They will react quicker than corals in my experience.

I will on this Cardinal but I haven't on the others. The tank is a rimless uncovered tank. The return from the sump is hitting off the top of the water as well. The MP40's make some nice waves too.
 
So, what I hear you say is that the ALL of the fish were swimming around fine and then the next day their dead or, upside down breathing hard?
Were these fish ever quarantined and were they eating at the store?
 
Sorry, I just meant, we will wait for the results, assuming the current fish passes. Do you do them or have someone else? I actually do them on my and other fishes at times, so curious.

Dying all at the same time is just strange. Especially if they were all eating well and acting normal.
 
I never did one but would love to sharpen up my scalpel and give it a whirl
 
I hope your find the reason for your losses. Other than your fish issues, your tank looks great. Nice scape! Good Luck..

Yes they all were eating and acting normally. They were never quarantined. I never found the Goby, one clown ended up in the mouth of an Acan, I found the Tang on the sand as well as the other clown.

Thank you!!!
 
The anemones will always be the first to react to swings in the water quality if they're acting up is usually a sure sign something is off with the water itself. i would take a sample of your water to an LFS for some testing
not sure where you're located if its NJ i can gladly send you in the right direction
 
One thing, reading through this thread. What about a hitch hiker? If ammonia is 0, and all other parameters are good, then there might be something attacking the fish. If the rock was cured BEFORE he brought it home and it by chance could carry in a hitchhiker.
 
Ok. I'm bringing the dead Cardinal in for an autopsy. But until then what do you think?

Yup definitely dead. sorry, I kid at the wrong moment. Sorry for you loss. I dont see anything from the pictures that tell me what happened.
