I might be loosing the whole tank tonight

[drawman]

Dang I'm sorry to hear that . Very good call on the water change and carbon.

Thanks for the kind words. I'm leaning towards the cucumber nuking the tank.....still can't find him....it was a red and black. The only two fish I can see are the clowns...and they are still alive. The Tangs are dead and suspect everyone else is as well.....don't see them. I'll wait until lights are on to start pulling them out.

I changed out the carbon last night....maybe I'll do that again this morning. In a couple hours I have another 50 gallons of new saltwater to change out as well. Also running the skimmer wet.

I'm in the dumps, to say the least.

Is it possible the cucumber is in the overflow, or got sucked into a pump?

 

[tripdad]

I would move any wave pumps up until they start sucking air and mixing it in. What I'm getting at is to start super oxygenating the tank. Not only may it help the fish but it can start breaking down some kinds of contaminants thru reaction. If you start getting a froth at the top of the water then look for something getting into tank.

So sorry

Prayers are with you. In times like this I wish we were all closer to each other to help out. Let us know how it goes.

Based on what I've read, I would lean towards it being the cuke. I had my entire 156 wiped out in the course of a move 6 years ago, in under three hours, when all livestock went into a vat of new saltwater (one week old, but clearly not what everyone had been living in) with no acclimation. As I think about it, I, too, had a pink and black cuke, and the stress of going into completely new SW may have set it off.

A agree with the others. Get carbon running -- perhaps even some of those various other pads that remove various chemicals -- as soon as you can, and put the fish in another container. Not sure if others have posted this, but I would NOT use 100% brand new saltwater. Rather, I would do a 50/50 with existing SW, to minimize shock, even though it sounds as if there's something in there. You could then do a series of 50% changes on the container where you have the livestock to titrate out whatever is in their causing problems.

I hope this helps. Having lost a whole system myself (with a LOT of expensive fish in there......), I know what you're going through.

Definitely check the heaters too especially if you use glass ones.

What are your parameters?

 

[redfishbluefish]

Thanks everyone....it helps.

Now here's what I found in one of the MP40 powerheads:

It is soft and mushy....about 1/3 the original length of the cucumber....could this be the skin after it pukes out it's innards?




Just waiting for 50 gallons of new water to get to temperature before changing. Running the skimmer wet and with the change of new carbon, the corals are looking a little better. Yellow Tang removed, two clowns and diamond goby accounted for, two pajama cardinals, scopus tang and melanurus wrasse MIA.

 

[TheEngineer]

Sounds like progress. Looks like that must have been the culprit.

Sorry for your loss

Oh man he was in the powerhead!

I've done a ton of research since this thread started on Holothura and their toxicity. Their guts aren't poisonous. But they can secrete holothurin toxin out of their anus cavity. The ones I have had pass on me, eviscerated their guts and died, disappearing into the tank somewhere. I have NEVER had one agitated to the extent that one obviously was! I am sorry for your loss, I am also sorry that I doubted he may have been the culprit! Everyday I learn a ton from Reef2Reef. I'm sorry for your experience. I hope you will be able to rebuild. I wouldn't put anymore cucumbers in there. My last one that eviscerated himself made me decide I was done with them.

 

[djd3mon]

I am so sorry for your loss. I hope your remaining fish will be ok.

 

[ngvu1]

Wow, a little cucumber can screw up 100 gallons worth of water just like that? I am following this....

 

[Marsr]

Curious as to the parameters as well. I'm guessing you aren't running Kalk in the top off water? If you are, I wouldn't be thinking about the cucumber, as the Kalk would cause the crash and your cucumber would die and potentially get sucked up into the pump as a result (but not the cause). Sorry for the loss, a friend of mine just had a minor crash due to palytoxin most likely...

 

[Alfrareef]

I had a holothuria that also disappeared and more than 10 fishes become dead. Funny that a yellow tang survived without any problem.
For me sea cucumber are out of my tank forever.
Your clowns are still ok?

 

[Cory]

Im not sure if carbon would do much for removal of this toxin, but id probably add some hydrogen peroxide to break it down.

I'm so sorry Paul! This is just terrible. Keep your head up though, I know you can salvage a part of this.

Posted before I realized there were multiple pages. Sorry to hear about your loss.
