Whole tank wiped out over night.

[uutank]

Couple days ago I noticed some problem on my anthias I thought it to be lympho, I started to look closely at it. Yesterday it got deteriorated at night and anthias was having all white slough over her fins she looked weak and was breathing heavily. I started to prepare water for qt tank so that I could transfer it to the qt this morning. Just right now Today at morning I woke up to see my whole tank wiped out. My two wrasses died right in front of my eyes. Anthias was already dead. Firefish and sand sifting goby are still missing. Only survivor is false percula I’ve just now taken it out of tank to qt. Please reefers help.

This solar fairy wrasse had beautiful bright colours it got faded away just like that overnight.

Except anthias all fishes were eating and they did eat last night also.

Parameters are perfect.

This is my tank.

Pls help what happened all of a sudden I’m at a loss. Plus I’m so much depressed, I treated all fishes for a month in qt and still something went in.

I'm so sorry for your loss! The way you described the anthias condition prior to death sounds like brooklynella.

Was there any new additions to your system recently?

Looks like from your FTS that your battling cyanobacteria or dinoflagellates.

Let's get some more eyes on this:

How long has this system been running?
Where did you get the rock?
If they were all eating last night what did you feed them?
What is your salinity?
Please tell us more about your filtration system and husbandry so we can try to help out.
They do not look like they have a parasite to me, perhaps the ammonia kit is bad? None of the other parameters would wipe out your fish overnight.
Sorry for your loss.

Yep, this right here. Brooklynella is nearly untreatable, because it kills so quickly that once you notice a problem, it's often too late. It's a very rough disease to deal with.

I thought Brook is usually associated with clowns and damsels?

It usually is, but can and does effect other fish:

That's good to know, but the anthias and all other fish are not shedding anything.. That is why I was thinking ammonia might be present and the API kit might be inaccurate..
Thanks for the link!

"anthias was having all white slough over her fins she looked weak and was breathing heavily"

Best guess given what the OP stated and that others died overnight.

Could be ammonia, but the OP's tank looks cycled given the nuisance algae.

Lack of O2 is a possibility on the wrasses passing, but anthias ethier had Brook or Velvet with a secondary bacterial infection. The later would have been obvious for sometime.

Velvet is a strong possibility, but should have been seen with a month in QT. This depends on what treatment was used during this time as well.

Need more info.

Skimmer?

Im thinking false reading from test kit as API is less than reliable.
Run a sample to pet store and have them test water and see what results they get compared to the one you got.
Sounds like an oxygen issue. Also is heater intact and not broken sending current into tank?

Yes the only new addition was the sand sifting goby, and I didn’t qt it as my lfs had it for over a month with him and it was basically the only fish he had as there are floods here in India, the fish industry is affected. I trust this lfs as I buy only from him, so he told me that the fish is good to be introduced in the tank.
As far as I’ve researched I’m zeroing in on marine velvet only, the only remaining survivor is my clown fish I’ve already started treating it with copper, it was breathing heavily and still is. But it is still alive in qt, hope I’m able to treat it.

 

[DeniseAndy]

I am so sorry for your losses. That is a tough night. It does sound like Brook on the anthias, but the others so fast with no signs is very disconcerting. I hope the clown makes it in qt for you. Maybe go fallow and make sure you are getting plenty of 02 exchange from a skimmer, airpump, powerheads hitting surface, etc.

Edit. Looks like you have a protein skimmer going. I am betting velvet or brook.

1.This system is over 6 months old( first 3 months it was fishless) it was only in the past 3 months that I’ve started adding fishes till then, all the cycle was complete. I got rocks from lfs only, they were dry rock, but live sand.
2. From start I’m feeding them a homemade mix of shrimps, Hikari marine S, brine shrimp, mysis shrimp.
3. Salinity is 1.024
4. Sump filtration, Reef octopus 200 INT skimmer, purigen, Seachem matrix carbon, Seachem bioballs. 20 gallon sump also one chaeto. 80kg Dry rocks, 80 kg live sand.

I have 2 dedicated qt tanks. I qt all fishes no matter what, except this sand sifter and I’m kicking myself for it. I’ve done water changes in this tank only twice in 3 months as my test kit never showed any fluctuations in parameters.

The anthias was eating voraciously all this while and the coloration was also beautiful on it. Only yesterday it left eating and looked weak all of a sudden. I don’t think there can be a issue of O2 as the wave maker does a lot of surface agitation and also this tank is in my balcony sitting area. See the photo below. Its more or less in an open area, so gases diffusion won’t be a problem IMO. Plus there was no signs of fishes gasping at anytime they were in my tank.

 

[uutank]

An update guys, I’ve found sand sifting goby in the tank it’s alive and swimming, though it’s in hiding. I’m still finding my firefish goby, but I’m unable to.

I don’t have a heater as in India it’s already very hot. I rather have a chiller and there’s no leakage of current whatsoever.

Thank you so much DeniseAndy. I really wish this clown makes it. I’ve a special place for him and my firefish in my heart as these were the first fishes, i ever got and they’ve been through my inexperienced reefing phase also. While other fishes here there died in qt they both went strong. Hence there name was hardy boys. I think the firefish the dead already somewhere in tank[emoji22], but I hope this clown lives on.

Any chance of environmental factors such as recent spraying in your area for mosquitoes or a neighbor fumigating? an outside open air tank would be very susceptible to things like that

Nice observation brother but I don’t think this might be the case. No spraying or fumigation, neither any odor. But there’s a house being constructed in my neighbourhood. But this has been going on for more than 5-6 months, and till now nothing happened. It all just went down last night, i don’t know what, I fed them well. And went to sleep. Only to see a sea of dead.

 

[Lasse]

Good - I think the most common cause of fast killing of fishes (IM ) - oxygen depletion is overruled. Still on the path of intoxication - can you exclude any toxic gases from the air. Herbicides, pesticides and so on? Industrial smoke or something like that? Do not forget - a skimmer is as good at putting gases into the aquaria as it is to take them away.
