Fish Dying - What is the problem ?

[onat]

Hello, i really need help. Please guide me. I set up a 90-gallon aquarium 2 months ago. While setting up the new aquarium, I transferred rocks from my old tank, which I had carefully maintained for about 2 years without losing any fish.

I added my bacteria to the new tank, and diatoms formed in about 2 weeks. During this time, I added 2 chromis and 10 inverts. (conch, turbo, nass. snail)

After the additions, there were no problems in the first month 2 chromis lived happy. In the second month, I added 2 firefish, 1 orange shoulder, 1 cleaner wrasse and 1 brown tang. I bought the fish and just acclimate them because they were QT fish in my LFS.

A week later, the orange shoulder and brown tang died. I'm sure ich and fluke formed and spread in the aquarium during this time.

3 days later wrasse and 1 firefish died and I saw signs of uronema next to one chromis, and it had died with its half skin red 1 day later.

Currently, only one chromis (with its mouth inexplicably half-open but eats food) and one firefish remain in the aquarium sometimes rubs against the sand

None of the inverts have died. The water is crystal clear, all equipment is working perfectly, and there are no nitrate or ammonia issues. Surface is all the time moves for oxg. exchange.

I'm not adding any fish right now. However, since the aquarium is large, it's impossible to catch any surviving chromis or firefish.

In my country. The only products i can reach seachem products. I have seachem focus, metroplex and garlic guard. I have cupramine, paraguard, cuprisorb. I am not able to catch fishes and QT them with cupramine. I love my rockscape glued the all fiji rocks together. I thought take out the all inverts, and cupramine to display tank but rocks and sand can absorb the copper.

What should I do?
1- Should I reset the tank, bleach all the rocks, clean all the sand and equipments.
2- Should I wait 1 more month for the aquarium to more mature with benf. bacteria further with major water changes? Because i think no matter what i do, in some point this diseases will enter the tank. If so, should I remain calm and wait for a more settled tank and add fish slowly one in the time ?

I'm afraid of buying new fish and see them dying; I want to keep tang and angelfish species.

That’s a tough spot to be in.

There isn’t any reef safe medications that will eliminate ich from a tank. Flukes can be removed with praziquantel, but I don’t think that Seachem carries that.

The best course of action would be to capture the two remaining fish - trying fish traps or at night. Then leave your display fishless for at least 60 days and treat the two remaining fish separately with prazi and copper.

Another option, not as good, would be to just hold these two fish in your display for 60 days. That is less likely to work because the fire fish is still scratching.

Video very short but points to water especially if inverts are fine. Do as Jay stated adding no fish and allowing tank to mature.
As for your country, you should have access to Waterlife Myxazin for bacterial issues, cupramine which you are using and should be applied in a separate treatment tank at .45ppm (max is .5) and seachem Kanaplex also for bacterial and for eye issues, Erythromycin.

I've tried everything to catch the fish, but they're too fast and hide in the rocks. One day I got frustrated and wanted to reset to tank remove the rocks, but they were too heavy and stuck, and I was afraid of breaking the glass if I lifted them. And too much work. I guess I'm left with only one option. I won't touch these two fish; I'll monitor them with routine water changes in the aquarium, and if they don't die, I'll add new fish in two months. If they die, I'll remove the inverts, turn the water temperature to 29-30 degrees, and leave it empty.

So, another thing is the possibility of uronema in the aquarium will never completely disappear, but once the tank matures, it won't cause me too much trouble with the right fish choices, am i right ? I'm someone who doesn't mess around much with the aquarium and very careful to avoid stressing the fish. I am very careful with the water parameters.

İf i mix seachem focus and metroplex with garlic guard and fish food. İf i feed this way just the details on the seachem website says. İs it good thing or waste of my time ? İn website seachem says it will help with ich.

Uronema is a normal inhabitant of almost all established marine aquariums - 80% or so will test positive for it through eDNA testing. This protozoan only seems to be a fish parasite on newly acquired fish of certain species. The normal Uronema found in tanks just feeds on bacteria.

Jay, How about removing inverts putting them in quarantine with normal salinity and treating display tank with hypo for 30 days at 1.009?

That works in some cases - it depends on how the reef is set up. If it was established with dry rock and all the inverts can be removed, that is a good candidate for that. However, if the live rock used was premium wild collected, the hyposalinity would nuke all of the encrusting flora and fauna that was an important part of the tank.

Got it didn’t think of that

Right now i will change the tank temprature slowly to 28celcius for ich lifepawn. I have no coral. Only 2 fish and inverts. Lest see how it will end after 1or 2 month. There is nothing to lose more. Maybe it helps a little bit for ich. Tank reset looks more difficult and there is no guarantee disease free option. Soon or later something will enter the tank. Best i can do is make my tank more mature and established with benf. bacteria
