frustrated! fish dead
 

So it seems my tank is doomed to only have 2 fish. My diamond goby and my clown. Seems everytime I add a new fish they die.
I bought a small blue yellow tailed damsel last week and he was doing fine.
I saw him eat. Then 2 days ago he started hiding and this mornig he is dead.
I dont understand it.
That's what happend to my other fish I've added aswell. So strange. =(

Ill do some tests on my water and post them later but my goby and clownfish are happy. =/

The tank is 1 1/2 old now and the salinity is o.o25. I dont have any crabs, I feed the fish once a day at night. they get fed some marine flake. Sometimes I put some shrimp in the tank for them.
I have a skimmer and koralia 2 in the tank for flow. There's no algae in the tank either.

Any ideas ?

Did you QT the new additions?

.

no i just put them in .. i dont have another tank to quarintine them in . Do you think thats the problem ?

Sorry for the loss of the fish. I hope the salinity is a typo. When you post the water parameters, maybe let us know what else you have in the tank. Ie. how much live rock, sand depth, type of skimmer etc... This may help someone pinpoint a potential problem. Also maybe explain the "putting in" do you do any acclimation procedures?

Good luck

yikes I may have found the problem .... I just measured the salinity today and its 0.027!!
I dont get it.. it was normal when I changed the water and I just added fresh water 2 days ago so I dont know hy its so high.
Unless I didn't measure the salinity in the change water....:sad:

ok I better get hat down. I want to get one the digital metres.. =/

I'm still hoping that's a typo, salinity should be between 1.024 - 1.026 or some where around there. Right now you are way too low.

yes im sorry imeant 1.027
sorry about that

asherah

1.027 isn't going to kill fish..

ok. I dont know why he died then. =/
He wouldn't be shocked because its too high or something ?

What are your parameters at? Ammonia/nitrites/nitrates/temperature ??

Is the one pump enough flow for a 30 gallon with no crabs? I'm sure there would be some pockets you can't see full of detritus and algae

Perhaps your existing fish are used to a possible imbalance, and new fish are dying from the extreme change???
