Sad happenings overnight

[Electric Monk]

Very sad day for me, I woke up this morning and Five of my fish were dead.

My, Copperband, Clown, Wrasse, Coral beauty and Grammer. plus one of my cleaner shrimp.

I cannot find out what happened in the space of the six hours I was asleep, i've tested everything I can and the rest of the tank is as normal. They were just laying on the bottom of the tank.

My Banggai cardinal, Cromis, Lawnmower and scooter are alive and well, as well as my other cleaner shrimp, all the snails, hermits, my two mithrax crabs, pink lobster.

I'm so upset right now i'm not sure if i'm going to carry on with the fish. To me this is like losing five pets not just five fish in a tank.

Devastating news, I was watching all these fish on your webcam and all looked full of life last night. I don’t know what to say other than I feel for you. What could have possibly went wrong in such a short time. Are your other fish healthy and well?

Thats really bad news, and even harder to bare when you don't know what could of caused it. Hope the rest of your fish are ok.

[SteveS]

nightmare...sorry to hear of your losses mate

dont throw the towel in, keep going....

are you any closer to finding a cause? ph swing/ lack of oxygen? seem unlikely...use any sprays in the room before bedtime?

give it a few weeks and go and buy a copperband, save someone else buying it who cant tend its needs

realy sry mate :(

[Gillybaby]

Oh no, gutted for you m8. I hope you find out what happened.

[Pinkfish]

Im sorry for you mate. Hope you find out what happened

[Electric Monk]

Still no luck here finding out what happened.

If anybody has ANY ideas please post them (I don't care if it's "Aliens landed and wee'd in your tank") Just anything so i can get to the bottom of this.

The tank, i'm looking at it now, is happy, fish are swimming about as if nothing happened, shrimp chilling behind the usual rock. polyps looking great, 'Shrooms out and looking good.

As a last resort i've changed out the filters in my RO unit, got a new mixing bucket, binned the batch of frozen food I got on saturday.......It's that 'clutching at straws time'.

----------------

On a side note, I'm so pleased I still have my Banggai cardinal and Chromis, they were the first fish I ever brought for the tank, the boys are still going strong.

Still missing the rest like mad though :(

Gutted for you, this really is upsetting.
Lets start at the beginning . What are your tank speks, stocking, equipment and how long the tank has been running and what you have done to the tank in the last week. There must be a solution for this. If we don't get to the bottom of it, it will do your head in.

I once lost a clown fish soon after it ate a piece of frozen. But honestly think it was a 1 off. To lose fish in this number overnight without any signs could be a poison. I know you are wanting wild guess work but maybe hairspray or furniture polish? That has since been removed by carbon?

Gues Guess and guess, You will probably never find out.

MT That is a better start, which I had raed before posting. Will watch this thread and but in with my guess work.

What a nightmare, this is so strange. I'm sure you've thought of these but here's a few thoughts:

Sharp drop of oxygen/increase in CO2?
Sudden peak or drop in temperature?
Powercut overnight which could've cause one of the above?
Ozone overdose (if you use it)?
Disturbance of DSB?
Something falling into the tank (know someone who had a problem when glitter was added by an over enthusiastic younger brother or sister, can't remember which)?
Is your tank earthed? Could it have been an electric current passing through the tank from a faulty powerhead for example?

Although, why only some of your fish are affected and no corals/inverts makes it less likely any of the above are the culprit. Just thought I'd throw them into the mix just in case you hadn't thought of them.

HTH and you get to the bottom of this soon.

yes very sad news sorry to hear it

[Reefer]

Bad news.
I had a tank wipeout early doors when I first set my tank up, introduced a coral beauty and boom it died without any symptoms, then my clowns and kole tang developed and died from white spot, very bad time couldnt even bring myself to look at the tank for a couple of weeks, but you do get over it. Keep going!

[oakwell]

Have you found anything further out about the tank or located the problem?

[Wilfy]

With what has been affected I would strongly suspect marine ich or oodinium (marine version of whitespot or velvet), it seems the logical answer as to why on certain fish have been affected and no corals. Some fish are hardier than others, not just types but individual specimens. Ok one shrimp but these can be temperamental.
About 6 months ago I lost my copperband and flame angel to this, one day fine, the next morning white specs had appeared on the fish and by the night time dead.
Never got to the bottom as to what had stressed them enough to get this as I had the fish for, flame nearly 5 years and copperband over 3 years.
Have just left the tank since then and not yet restocked, I have a yellow tang so any fish going in will be stressed if he gives them a hard time and could cause another outbreak.
In the tank now I have yellow tang, 2 clowns, six line, scarlet hawk, 2 ytb damsels.
The scarlet hawk did get it but was strong enough to fight it off.

Hopes this sheds some light.

I have never experienced the likes of Oodinium, but did not think this would affect the fish so rapidly?

It is awful when such losses occur, but you may never be able to nail what actually caused this.
