This is wierd :(

[Reefer333]

The only other fish I have is a fire fish and he looked fine last night. The BSJF's color looked normal.

Stefan, any news? Hope it's not too late, but a big water change is in order, like 50%!

[naperenterprise]

I agree with Greg on this one.
Do the water change if you havent allready, and maybe run some Ox threw the tank via an air pump with wooden air block.

Also what is the temp? Did you heater go into over drive??

Hope all is well.

Thank you all for the help but I lost both my clown and my Blue spot I don't know what could have possibly killed them. My clown was in my tank for 8 months and was healthy as could be. He went from great to bad in probably 4 hours. I really wanna figure out what happened so no one else will make that mistake, and because I plan on trying one more BSJF after I figure it out.
Here is what I did that day:
Changed foam filter- I rinsed it out with R/O water

Replaced phosguard- I rinced it out with R/O Water too

Turned protein skimmer on- I've been trying to get it working for a week. It was blowing out small bubbles. I did run it all night with the little bubbles coming out. They were not that bad tho

Put an Foam after protein skimmer to try to diffuse some of the bubbles.

Tested water and everything was perfect (or close enough)
Water temp was at the regular 77-78 (I use a digital thermometer)

Fed a new brand of mysis that I bought at a LFS (Hikari), the day before all this happened I soaked them in Seachem's garlic. They both ate. The next day they ate too. All this did happen after I switched food (but firefish ate too)

There is also a tube anenome in my tank that was near the BSJF hole. Its small tho and I havent seen it get close to my fish.

Thats all that I did to my tank in the past 48 hours. My firefish is healthy and shows no sign of stress. All my corals are thriving and also show no signs of stress. I really hate that both my fish died was a very bad day yesturday and whats worse is I don't know what did it.
Thank you,
Stefan

Did you disturb the sand bed at all? in the past week week and a half?

[Dentoid]

I'm so sorry Stefan.

[Varga]

Condolences

[Reefer333]

Thanks Scott!! The jawfish deffinatly disturbed the sand bed when he was building his mansion.
Here is a pick of the Skimmer

Here is where the tube anenome is, if you look close you can see the BSJF

Thanks Varga

Sorry about your fish. I lost my BSJF last week, and it was harder than any other fish I'd lost. And clowns seem to wiggle their way into my heart, too, so I'm sure that was hard.

[Scouter Steve]

So sorry to hear Reefer. Have you got a concrete reason why this happened yet? I and others have stated ideas but what would frustrate me most would be not knowing why. Again sorry to hear of your loses.

[KimPossible]

That is definitely weird and extremely bothersome, like you said, how are you going to prevent if, if you don't know what happened in the first place.
So sorry to hear

[lcstorc]

So sorry for your losses. I know how hard it is and I agree I would love to find out what happened so we can prevent it in the future.
I don't think it was the mysis unless there was some bad batch or something. I have feed Hikari many times and it is what Matt recommends for seahorses so he must have good experiences as well. The only thing I can think of as a possibility with the food is if you thawed it in advance and left it out or even in the refrigerator(longer than one day for refrigerator)
When you cleaned the filters and such did you use anything other than RO water. Maybe some cleaner of some kind. Even if you used a sponge or brush that was used with cleaner that would be a possibility.
With the skimmer off for only a week I don't think that is it but I certainly could be wrong.
The same with the sandbed. How long has the tank been established? It takes some time for dangerous sulfer to build up under the sand. Now if it is an older DSB then you want to look there.
What about the rubble for the jawfish's home? Where did it come from and is there any chance there was cleaning solution or any type of contaminant there?
Bluespots are notoriously difficult to keep though very wonderful so if something was wrong I could see that as the first to go but clowns are generally very hardy and I would have expected the firefish to go before a healthy clown.
The think I know the least about is the Phosguard. I have never used that brand so that is a possibility but I really don't know.
Has Leebeca chimed in on this one? If not you may want to PM her a link. She is very knowledgable so she is likely to have ideas of things I would not have a clue about.
Also post the numbers on the parameters. Fine or near it really doesn't give much info and I can guarantee that is the first thing she will ask for.
Sorry that all I have are questions. I really feel bad for you,

[Reefer333]

Thanks Lynn!! I only soaked the mysis for two hours so they werent out long,
I only used R/O water to clean foam filter no cleaners, rubble rock came from LFS and I took a piece of my live rock and broke it for him, tanks been established for 7-8 months, the clown and Jaw did stay in the same side of the tank(trying to think of all possibilities), I had manderine die about 2 days before all this happened he looked healthy but stomach was huge(I do have a lot of copapods in tank tho, but still don't know what killed him). The thing that drives me crazy is if there was a contaminate in tank wouldnt my firefish and corals be affected? They are all thriving. And the fish got bad in a matter of hours, and you should have see how healthy my clown was. I did take phosgaurd out of tank till I figure this out. Oh yeah and I did take a clean/new toothbrush and clean the red slime off rock before this happened (I did rinse Toothbrush off with R/O water too).
Here are my parameters:
Temp 77-78
pH- 8.0
Alk 161.1 ppm kH/9 dkH
Cal 460ppm
Nitrate-0
Ammonia-0
Thanks for all your comments!!! One day I will eather be broke or a successful Blue Spott Jawfish owner

Hmm
I wonder if the mandarin is part of the equation? Did you make any changes before the mandarin died? They are pretty delicate so whatever it is could have hit that first. I am assuming you removed the mandarin pretty quickly or you would have mentioned it.
As far as the problem hitting the firefish and corals there are many things where the corals would be fine, but it is a bit odd that the firefish are doing well.
What do you have in your cleanup crew? Any chance of a mantis in the tank? I would think either of those would be an immediate death or at least have immediate signs.
I'll admit I am very puzzled. See if you can get Leebeca to look at the thread. She will likely have ideas I have never thought of. Hopefully my questions and your answers can help her with some ideas. I really wish I knew the answer for you.
