Mystery Illness

[fluttermoth]

Any one got any ideas on this?

I had seven (bred by my mum) emperor tetras in my tank. i've had them about two years; an all male group. About a month/six weeks ago I added six Congo tetras. Everyone was healthy, both kinds of tetra shoaled together and everything was fine. Then a week ago I added six more Congos, and now my emperors are sick with 'something'.

One looked a bit bloated and an odd colur on thursday teatime and it was a bit quiet; it was dead by the evening; it happened really fast.
Everything else looked fine until last night when I fed them, they were all in one corner as if they'd had a fright from something; apart from that they looked fine, but I found another one dead this morning.

I've netted them out and got them in 20 gallon tank with a few plastic plants, a filter with ceramic rings from the main filter and a heater (at 78°F/26°C)

Main tank is; 48x15x18"

stocking is/was
7 emperor tetra (now 5 in a hospital tank)
12 Congo tetra
1 4 inch black angel (was one of a pair but he turned on his mate one day and I had to re-home her)
7 Corydoas adolfoi and eight cw021 cories.

Stats are;
ammonia 0
nitrite 0
nitrate 10/15ppm (I have done an approx 50% wc in there as I took the water from the hospital tank out from here)
pH 6.8

temp 76248F/24°C
APS 2000lph external with ceramic rings and bioballs
Was set up with cycled media from another tank about six months ago

Never had any health issues with any of the fish before now.

All the other fish seem happy and healthy and look totally normal.

I can only asumme that the second batch of Congos have introduced something that they, and everything else, is immune to.

Anyone seem anything like it or have a clue how to go about treating it? I don't have any meds except something for whitespot

I'm sorry to hear about the emperors. Unfortunately, I don't know what it is. I had a similar thing happen before, but I never did figure out what caused it.

I've lost another two now too; one last night and one this morning; I'm treating with salt baths atm, but it doesn't seem to being doing much good

 

[colleen0309]

Are they swimming ok? Mine seemed to swim funny right before they died.

 

[fluttermoth]

Yes; they swim fine; they just don't want to; they're just all stuck up in one corner

 

[colleen0309]

i'm so sorry. I wish I had better news. I lost all but 1 of mine. Mine seemed to swim erratically at the end. It didn't seem as if it was something I could treat, it happened too fast.

 

[fluttermoth]

It's awful when thwey show no proper symptoms isn't it? It does happen so fast; I have no idea what the %&@£ I should treat for even.

 

[Sam-Baker]

Isolate the fish and treat with Anti-Bacterial-Infections or internal parasite. The interpet range is a good range to pick from. I would use a general anti bacterial/ internal parasite one for now just to see if it makes a difference, if it doesnt still complete the course as you dont want your fish or the bacteria becoming immune to treatment by only using a half course


This is what i would do in your position as there are no external symptons it must be either internal.

Sorry to hear some already havent made it.

Potentially a bad mix with the Congo's? Perhaps stressed them out too much...would be my first guess.

 

[fluttermoth]

I did think that, but they were fine together when I got the first six Congos..I've lost another two while they've been separated in the hospital tank too.

I've got them on a course of Myxazin atm; hopefully that'll do something; I came to the same conclusion as Sam that it was most likely some sort of internal beacterial infection.

Its the only thing i can put it down to so... keep me posted on this one. Anymore questions or problems arise just list them

Yes I'll update the thread in case anyone else ever has anything similar

They're all looking fine today, so far (*crosses fingers*)
