Fish die corals live

Any input is appreciated. What perimeters can kill fish. But no effect on corals ? My fish keep dying. But the hammer and Zoas are unaffected.
 
Question is how much do you feed your fish? Are they still looking for food and hungry?

How long do you have them for them to Die?

What symptoms do they show prior to death?

Do they lose colour? Appetite? Change behaviour?

What live stock do you have?

I think before we can help, we need a lot more information.

P.s. corals take a long time to starve to death. Also will appear normal before suddenly dying off from water quality issues.

Thanks. I was on phone and posted out of frustration. What I have is a 4 months old 90 gallon. After cycling for a month using Dr Tims one and only. I added a Yellow Tang. a few weeks later I added a Blue tang. Then a couple of clowns. All was well for at least a month. Then I added about a dozen of various snails and crabs... Clean up crew.
Started getting a lot of red bacteria before the clean up crew. After the bacteria continued to get out of control. I tried the Tim's waste away. The next day the fish died. I finished the treatment. the rocks are clean. I put the Dr.Tims Gel wast away in. Did another 30 percent water change and waited a few days. The few corals I have are opening fine. The cleaner shrimp is doing great. The clean up crew are all moving and doing great. No2,No3, PH, Ammonia... are all great. Put a Golby in today, and it died within hours. The shrimp and snail are chowing on it now. Thanks for the reply's
 
I assume the red bacteria are cyanobacteria. They thrive on phosphates. - water quality issues.

The fact your Goby died in one day says it's definitely water issues.

Can you take a sample to your local fish shop?

Was the goby behaving erratic?
Rubbing it self?
Gasping?

Is there a film of protein on the water surface?

Do you have a protein skimmer?

I can take a sample to local store. Goby did hide. then I saw it laying lifeless. I do have a protein skimmer, but it is not one right now. Due to the cyno treatment. But it was on during the treatment, but with the skimmer cup off.
 
It's normal for fish to hide when they are new.

Do a big water change. Turn on skimmer.

Are you sure you don't have a hitchhiker that's not attacking the fish?

Turn the lights out, use a red light to see if there is anything creeping about.

Your problem could be disease, food issues, or the ability of the water to carry oxygen, which can be due to the skimmer being off (it oxygenates) or the treatment chemicals. As a rule, do not add magic cures to your tank. Red Slime Remover is not in itself a bad treatment, but when coupled with low oxygen in the first place (the skimmer off) or poor water conditions what is ok can turn into a problem.

Cyano in itself is harmless, or reasonably so, unless it shrouds a coral and keeps it in the dark. It won't hurt fish. Red Slime Remover I have used---once and long ago; I prefer the 3-day darkness (lights off) once a month and aggressive skimming as a cure for cyano. Consult online for your issues before you let your fish store sell you a magic cure in a bottle. A 90 gallon should give you a lot of leeway, but it can also present math problems when calculating a dose---but you should know fish meds and doses for fish not intended for eating are NOT monitored by the FDA, and most anybody can put something out there and call it a miracle in a bottle. That said, many are good. But some aren't. And if you use more than one at a time it's a potential problem. If you'll take care to get some Salifert tests for the items in my sig line below, and use calcium, dkh buffer and magnesium to adjust your tank to those parameters, that will help both corals and fish. I'm so sorry for the troubles you've had. We've all been there over one issue or another, or it just hasn't happened yet. But your problem is (my best guess) an intersection of no-skimmer with low-oxygenation, most of it produced by the med and the instructions, which are not appropriate for every tank. Red slime is just something new tanks tend to go through, and if you go lights-out once a month for 3 days and skim at your most efficient, that's the best way to beat it.
 
The chemical red slime treatment most likely quickly oxidized the organics thusly depleting oxigen.
Fish suddenly die and inverts can handle the temporary lack of O2.
Sorry for the loss.
 
You can run the skimmer when chemical treating just take the cover off and let it overflow, then you still get the oxygenating from the skimmer without the removal.
