Help!! All of my fish are dying

[kristi518]

I have had my tank set up for a little over a year. I have a 60g with 100lbs of lr and 50lbs of ls. I had two mated clowns, two damsels, and a mandarin dragonet. The dragonet was the first to die but then about 2 weeks later I noticed that my clown was acting strange. So, I called the lfs and took in so water from them to test and everything came back normal. Then about 2 days later my clown died and then a day after that my other clown died. Now all that is left is my two damsels and I few crabs. I have no idea what caused my clowns to die. All of the tests that I have ran and the lfs say that the water condition is fine. What gives??

You need to pick up a test kit and check water parameters yourself.
We need actual water parameters to help.
Is the LFS using strips to test?
How long has your tank been set up? 11/07 right?
I've been reading through your posts.
How do you clean your substrate and is it still crushed coral?

Ph: 8.3
Nit: 0
Nitrate:0
Amon:0
Alka:180
Salinity: 1.026
I have had my tank set up since August of last year.

Are those your results or the LFS?
Any poisons used in your home lately? For ants maybe?
What are you feeding?
You lost 3 fish, but show 0 ammonia. You must have removed the dead fish pretty soon after death.
Were your fish aggressive toward one another. 4 damsels in a 60 should be OK. What kind of clowns?

how long has these fish been in the tank? has the fish been eating? what was the mandarin eating? mandarin usually need live copepods to feed on unless you get lucky and get one to eat frozen foods.

The 2 clowns have been in the tank for about 9 months, the mandarin we had for 8 months, and the 2 damsels we have had since we started the tank so for over a year. The 2 clowns and the damsels loved to eat, they never missed a meal and that is how I noticed that something was wrong. The mandarin ate the copepods that were in our tank, so when he died I thought that it might be the lack of food for him but then the clowns died two weeks later.

We do have an exterminator that comes to our house but no where near the tank. He only sprays outside.

 

[errattiq]

Do a large water change (like 40-50%), just in case by some chance there was poison introduced by the exterminator...either way, it'll dilute whatever the issue is fast..

 

[socal57che]

Is there a chance that you inadvertently introduced a toxin? I always wash my hands before handling the fish's food. Say I pick up the newspaper from the driveway that happened to be laying there when the exterminator sprayed. If I walked inside, dropped the newspaper on the floor then fed the fish, I could introduce the poison to the fish.
I agree with erratiq, do a couple good water changes and start running carbon.

has your temp raised above normal,also did you take the fish out or did the crabs eat them?

 

[mcbdz]

Another question would be, how are your inverts doing and, what are they?
Can you show a pic of your tank?
Do you check for Phos?
What is your maintance schedule like?
Just tryin' to brainstorm.

As soon as the fish died, I removed them from the tank and all of my crabs are doing just fine. The temp remains the same I have a reef keeper to help. Every week I do a 10% water change with Ro/Di water. This is what is so weird nothing really changed in my tank, everything has been done like normal week after week. Last night, I finally moved my last to damsels into another tank until I get this figured out.
