Rapid fish deaths why

[bucksfan1976]

Went to work everything fine

Came home and found the following dead

Powder blue
Queen angel
Flame angel

Water tested ok, no other fish seem sick, it couldn't be ich bc it can't kill in 8 hours can it, the queen was my favorite almost makes me wanna shut it down, not to mention I lost a exquisite wrasse 2 days ago to the carpet

Whats your water temp? Coulda had a heater explode.. happened to me and I lost all of my fish.

 

[bucksfan1976]

76.4 I have a reef keeper hooked up to prevent that

 

[Sdoutreefer]

gotchya. well im not sure. I am not very good with determining fish deaths. But I am sorry for you loss. I hope you stick with it and don't shut your system down!

Check for stray voltage in the tank.


Otherwise, I'm assuming the fish looked OK....checking their gills as well? Velvet hits fast and causes rapid death.

omg....i would cry if i lost my fish.....i never thought about the heaters having issues..one of my heaters looks cloudy inside..should i take it out..they are both glass heaters

Ok meter set on ac 200v (lowest setting) I test tank and I'm getting 00.5, now I thought I threw it away I had a (I thought different mixi jet) behind the rocks I unplugged it befor I tested I put it in a bucket with water read 00.0 then I turned it on an it read 01.8 so could that be the issue, these fish were perfect less then 10 hours ago so together when I had the maxi running I. The tank it would have tested at 02.3

How long have the fish been in the tank? Any new additions? Do you QT?

 

[jdl513]

Any chance of a power outage?

 

[bucksfan1976]

The fish were Qtd for almost 6 weeks, they were all added about 5 days ago

Sounds like there is something seriously off in your system...that low of a voltage is not a problem. What is your temp? That would be the first thing I look at. What other fish do you have? Ive had four small fish magically disappear over night in the last few weeks but I don't think our problems are related.

 

[bucksfan1976]

its always between 75-77 depending if halides are on.

 

[bucksfan1976]

Ok well I think I have a velvet outbreak or another type of fast killing parasite. Seems to have only killed the fish that were added most recently.

Queen Angel
Flame Angel
Powder Blue Tang
African Blue Tang
Citron Goby
1 Ocs Clown (clown had been established)

Other fish are not showing signs so I am not going to stress them by trying to pull them all out and re QT them again. However no new fish will be added for awhile. I am going to keep up on tank maintenance, keeping it clean as possible. If the outbreak continues, I will Remove all fish, however I will only be stressing out the fish even more then they are. I went through a simular issue like this 2 years ago. There was a sudden die off of fish, all of the survivors of that are still alive. Eating and doing great.

If it is a parasite? the tank must be left fish less for around 72 days. Or the problem won't end.

 

[bucksfan1976]

I agree. Im still trying to figure out what it is, I kept a fish frozen and Im actually gonna take it to a marine buddy at Ohio State and let him verify. I also went to the vendor to see if they have been having complaints. If I find out its a parasite then I will set up the 40 Breeder and put them in QT but I dont want to pull fish only to find out it was a stress issue.

Could the chemistry in your tank have been different than in your quarantine tank?

 

[bucksfan1976]

I try to keep them as spot on as possible. I mean it could have been stress, seeing as though besides a clown they were all introduced at the same time.

 

[Fishman793]

Do you have enough oxygen exchange going on? I had a glass cover on my tank and everything was fine for about a year until one day when the oxygen level dropped enough and everything died in 1 day.

 

[bucksfan1976]

Fully open top, 900 GPH on the return creating a TON of surface water movement, they all died over a 24 hour period, the 2 angels and the powder blue tang and african blue tang all within 8 hours. I found the citron goby this morning but it could have been dead and i didnt see it.

My guess is that they were not acclimated to the new tank salinity and temp correctly. Velvet can kill very quickly, but I think you would have seen it.
