First Flame Angel dies, now more fish are dying... HELP

[Lee1977]

Posted yesterday about my Kole Yellow Eye looking pale and recently losing a flame angel. Woke up this morning to a dead clown and my tang is not swimming alot. Just fed them and he didn't go after it like he normally does.

All params were fine as of yesterday. What could be doing this???

It could be a parasite of some sort. A pale color, is usually a stress reaction in fish. Stress from addition to a new environment, or being antagonized by another species - is normally expressed with a darker color, and the appearance of stress bars. A pale color, can be an indicator of poor health. It's difficult to say if you are dealing with an external parasite, or an internal parasite - since you don't mention noticing anything else out of the ordinary. Since fish often consume one anothers fecal matter, it's possible an internal parasite has spread inside your system. The other possibility is a bacterial infection, though if your water quality is good, this is less likely. Can you post your water test results: Salinity (SG), PH, Ammonia, Nitrite and Nitrate.

Ok I just read your other post. It would be helpful if you posted exactly what your numbers are. You say they are fine but your other post says you were adjusting pH. It seems something is really stressing these fish out.

According to my tests as of 5 minutes ago:

Salinity - 1.021
Nitrate - 0ppm
Phosphate - 0ppm

I don't have an ammonia test.

 

[Lee1977]

Ph is 7.8

Anyone???

 

[reeffirstaid]

How long has this tank been running? Do you carbon dose? Without carbon dosing, and the fish load you describe, nitrate of 0 would be hard to obtain.

 

[Lee1977]

Running for about 5-6 months. I run carbon in the sump. According to 2 separate test kits (one of mine and the other at my LFS), my nitrate is around 0.
Could this be an O2 problem or maybe a bacteria?

 

[Bad Company]

Stray voltage? Copper or other contaminants? If O2 was a problem they'd be gasping near the surface.

 

[Lee1977]

No, no voltage problem.

How did you cycle your tank?

Just sent a video of the fish to my guru at an out of state fish store. He says it looks like a parasite. Pulling the fish and putting them into a copper tank.
