Fish are stressed & dying within 24hrs

[YellowFinsReef]

How many gorgs and how large, also, what lps? I only ask, because those corals are not overly compatible depending on number and species and will cause issues to each other. Not the fish issue though.

Just under 6in for all corals. For lps I have trumpets and goniporas

could be ammonia or a bacterial bloom that sucked all the o2 out of the system. Do you have a protein skimmer or some way of o2 to get into system?

 

[DeniseAndy]

FYI, as the gorgs grow (depending on species - although holds for most common gorgs), they will out compete the lps by toxic warfare. If you notice your lps shrinking or just not thriving, I would suggest moving the gorgs. 6" isn't bad, but they are pretty brutal with lps expecially. FME

Yes, there is a skimmer too. That's why I was so confused. The only thing I could think of is osmotic shock. But that's never happened before. I've brought down fish as low as 1.015 from 1.026 in the past and they're still with me.

This could have happened while you were gone. I dread vacations or absence from my tanks.

Will that impact fish though?

 

[DeniseAndy]

No extended bellies? Man, you may never know the actual cause, but I doubt (just gut feel from my experience) it was not the salinity change. Maybe temp, but that usually takes a few days.

 

[DeniseAndy]

Will that impact fish though?

Nope! Just future consideration. I always warn people with gorgs. Since I have over 13 species I have lots of experience with them and their toxic ways.

 

[YellowFinsReef]

I'm just really adamant about saving these fish, because this is a reef grow out tank for my high end fish. My Madagascar clowns have died, my harlequins filefish have died. Now I'm super worried because i have a bonded pair of red tail tamarin wrasse and a bonded pair of radiant wrasse that will follow the same fate.

Ugh, I have a love-hate relationship with this hobby.

 

[DeniseAndy]

I would hold off on adding more, try to find the wrasses. If they actually died, could have been an ammonia spike on the rest of the fish. That is a small enough tank for that.

 

[DeniseAndy]

I get it. Anyone able to do necropsy? I do them on my fish when I can. Helps narrow things a bit at times.

Nothing new has been added. It was doing so well until last night. Then things started dying.

 

[DeniseAndy]

By the way, since I did not say before, I am sorry. I hate losing fish. Especially if I cannot find the problem.

 

[DeniseAndy]

wild caught fish? I would love to see what the livers looked like. Sounds strange, but that is the biggest issue I find in my necropsies. Liver necrosis.

The salinity swing is not the culprit. When LPS gets puffy, that often speaks to low flow or engaged in feeding. Did you lose power overnight, or shut off pumps to feed, or feed more than usual, or old food?

The fact that it seems to be adversely affecting fish and not corals suggests oxygen levels or how fish take in O2. This could be pumps being off, ammonia, or a pollutant/toxin. Coral toxins are usually focused toward other corals, that is not happening here.

Unrelated, but wrasses don't form bonded prs.

Thanks for that. I'll check again.

What do the full water parameters look like other than salinity? Do you have a clean up crew in there? Are they dying off as well? What types of corals are in the tank?

 

[Darryl]

what are you using to check salinity &
temp

 

[Benqb007]

When was your last water change and what percent? Also, what kind of filtration do you have running?
