A sad, sad day for FishyFishy

[Reefpins10]

My heart goes out to you for losing the fish . I had lost all my fish from ich within a month too, so I totally understand how you feel right now. I am so sorry for you, Fishy.

Oh, thats very sad! And frustrating too, I wonder if the mysis company would be willing to test the food and see?
I am sorry for your loss

sorry for your loss but all these fish in such small tanks????!! My guess is they died from lack of oxygen from the temperature rising.

That's a lot of fish in such a tiny tanks.

Contaminated mysis? I think not all the fish would have died...unless it is poison and if it is poison then other things would have died as well. Surely the invertabrate ate some too, and they would be dead too.

BTW, was that PE Mysis? because those are freshwater and are unlikely to carry any saltwater disease or bacteria.

I have 3 small tanks right now, and I came home to find all fish dead in 2 of the tanks. All my corals and inverts are doing awesome still. Water perameters are perfect. The only thing that I can think of is that I got a bad batch of Mysis. I know its a long shot, but its the only thing that the two tanks have in common. My third tank that I feed pellets only too was totally fine and normal. I opened the package on Tuesday night, fed the BC29, and the shallow tank that night with Mysis, the BC14 with NLS pellets. Wednesday afternoon, I came home to all fish dead. Not a single one left in the two Mysis tanks...

I lost the following fish, but nothing else! Inverts are fine, corals are looking great...

1 X Maroon Gold Stripe CLown
1 X Flame Angel
1 X Kole Tang
1 X True Perc clown
1 X Tailspot Blenny
1 X Black back Butterfly
1 X Bi-color Dottyback
2 X Black Yellowline Damsels

A sad, sad day for FishyFishy... and an expensive one.

Hey Mike. I'm also really sorry to hear this. I know you must be bummed.

I'm not convinced it's the food. If it were the food, you might expect one or two fish too tough it out. You might also expect them to show signs of distress over a couple of days. That's not to say that it couldn't be a toxin in the food that kills rapidly, but if that is the case I think we can expect to hear of other occurrences in the coming days.

The oxygen theory is plausible. It's worth exploring, but also seems unlikely to hit both tanks simultaneously. Stranger things have happened.

I'm not sure that I can help with the answer, but there must be one. I know it's cruel, but I would be tempted to buy a 'canary' fish and see if the tank water is the culprit. If he was fine in the tank, I'd feed the mysis. I would document everything and if that killed him I would threaten the manufacturer with a massive publicity campaign. With proof in hand, they might settle.

At the very least, I wouldn't throw out the food just yet. Nor would I really suggest using it ever again.

Oh No! So sorry to hear this Fishy.
Best of wishes on a speedy recovery.

So sorry to hear that Fishy. Hard to say what happened, except for your hunch.
Scary because we feed Mysis, too. When your other tank is not effected, that's pretty suspicious. I know that you would have racked your brain thinking of the common link to what has happened.
