All fish dying!!!!

[bryanb85]

please read and help!! Ive had my 75 gal set up since last sept. Started with live sand, month and a half later 75lbs dry rock. Added a nice CUC. Introduced 5 chromis in nov, few weeks later 2 cardinal, then an angel. Everything seemed to going great.

2 weeks ago i added 2 clowns and a hippo tang. All was still good. 4 days after the tang jumped out!?! Then 2 days later, waking up i had a clown floating, the next morning the other clown and a chromis. The fish all seem fine during day time hours but dwindle off during night time hours. The process continued until today where i have only 1 cardnial left in the tank. No corals in the tank yet, just sand, rock, and cuc.

All water checks were/are perfect, CUC is still truckin. LFS had me try medicated caviar and no ich, that didnt save them. We are all stumped.

Has ayone experinced this or have any clues to why the fish just took turns dying off?

Did you Qt your animals? Were the fish flashing an scarping on the rocks? If so I'm leaning toward velvet but picture of the dead/dying fish would be great for a positive ID on the disease.

That seems like a lot of live stock in a 75G. I second TheAngelfish. Did you QT the fish?

I did not QT my fish, this all happened within a week and a half. This is my first ever salt tank and also my first hiccup. :/ some fish were discolored and more bouncing into the rocks as the seemed paralized or no effort to swim

These might help

Please describe the appearance of the chromis that died. What was the behavior of the fish that died?

 

[bryanb85]

The chromis would be fine when we went to bed, as we got up to feed, one would be barely swimming bouncing into rocks and flowing with current. The fins had what might appear to be ich but was not very prominent. A little discoloration

 

[snorvich]

With so little information, I am guessing. Since you have chromis involved, and such high mortality, most likely would be uronema marinum. However, if that were the case, there would have been more discoloration.

Well I appreciate all insight. I only have little info due to being new to this hobby and everything happened so fast! My last fish (cardinal) is looking to be turning for the worst. I'm gonna do a big water change and see where it goes from here.
