Tetra dropping like flies...

My fault

 

No obvious signs of things I recognize.
One with a knick in its spine / tail I think.

 

So this morning the shenanigans started again....

I've added 2 pics to this gallery I linked before showing a glowlight that went uber stationary over night.... Just sitting dead still in his little enclave and refusing to move even if I bring my hand near (EDIT: not for food either). Also seems to have lost some colour. Also added is an image of a neon black that has decided to start swimming tail down... great. No other signs I can see.

I think they're going to be expelled in short order. For fudge .... :cry:

EDIT: I turned a very small PC fan on the tank after the temps started going past 30°C in the afternoon. Over a number of hours this brought the temps down by about a degree/hour until this morning it was sitting pretty at 24°C again. Could this have contributed?

 

Grrrrr. It's quite a fast cooling down.

 

High temperatures reduces the dissolved oxygen in your tank, add airstones if you don't have, get the surface of the water moving to increase oxygen in the water especially during hot spells.

 

May be that I cooled it down a bit too quick, but it was that or far worse outcomes described in another thread. And yeah Jwh I'd read that before so I put my filter's snorkel on so it could aerate the water.

The 2 fish mentioned somehow came right and I was just getting happy when a cardinal suddenly up and went to the aquarium in the sky with no warning.... Sigh.

Folder once again updated with pics of dead Cardinal and some Planaria(?) I found on it's corpse. Most of what I've read about planaria (not detritus worms as far as I can tell) is that they're not much harm. Opinions?

EDIT: I've watched keenly and never seen any parasite actually on a live fish (save for the ich I mentioned). IMHO these worms were only scavenging.

 

OK so, along with a dead fish today comes with a slew of new observations and symptoms.

I get home tonight and as I put my foot in the door I see something WEIRD happening in the tank.... one cardinal is having a royal freakout. It took some time and actually moving/removing some scape in the tank, then waiting for it to go again to get like a 5 second clip of it actually happening, but I did.... I also got some other footage of more symptoms: Laboured breathing, Red gills? What looks like a beige sore on the aft of the body and a sagging tail fin.



What's more, IF YOU CLICK HERE you can see that one of my bloodfins has some interesting stuff going on with his insides. This is NOT normal.

I'm still speachless.... what the hell is going on with my tank????

EDIT: Incase it's not clear the fish that's now dead is the guy in question... trying to save the others but I don't think that's working.

 

I'm as much at a loss as you man. Are you removing the fish as soon as you see symptoms? I would do that, just to give the remaining fish a better chance of survival. In presence of an unknown disease, treat it as highly contagious.

 

I think at this stage it might be safe to assume the entire tank is infected. How many fish are left? Absolutely mystery, and a terrible situation.

 

Yeah I'm halting all acquisitions until this is either over or all the fish are gone. :/

I dunno @BadgerBadger prob. about 25 fish.

 

I don't know if its been asked yet, but when a fish dies, do the others get a chance to scavenge...? Even a little bit?

Its a bit of grim question, but its something worth considering? Seeing as we're running out of explanations for this bizarre (and grim) situation.

 

Are these eggs or cysts in your bloodfin???

Though not all symptoms show up I am still thinking about NTD.

 

My research in conjuction with all this new info is starting to point me towards Columnaris.

EDIT: Specifically Strain 2 mentioned here.

 

That's false NTD. Saw loads of threads about that, but never like this. So far I never encountered real NTD, so I am not sure but this is soooo different than other cases and so lethal

Maybe @Vis can tell more.

Regards Aad

 

One or two fish I'm unsure of but the last bunch I've removed pretty quickly and/or before death. I haven't seen any scavenging.

I don't know how to tell. The lower bits seem like they are slightly yellow-ish whereas the upper "fuzz" is more of a cloudy milky effect. This is VERY hard to capture accurately on camera.

 

So I've been treating with PolyGuard to see if we can nip this in the bud, and then this morning this happened. Sigh, coincidence? Who knows? The fish somehow got trapped there but whether this was from being weak or otherwise.... I dunno.

 

Since this forum plays fast and loose with the concept of time it's hard to say for sure, but it looks like we're at 2 weeks without incident, about 3 since treatment started... which stained my stuff, but is fair to say saved the rest of my fish. We've been off antibiotics for a week and still everything is going fine.

Shall we say I have new policies on quarantine.

 

Glad to see that things seem to be sorted.

 

Sorry I didn't see this before , I had exactly the same thing in my neon tetras and lost loads of them , would always only end up with 2 or 3 surviving which I put down to basically survival of the fittest, I ended up just like you putting in a better quarantine system and all new fish are treated with seachem stress guard for the first 3 days then keep them in quarantine for a total of 2 weeks , since doing that I don't even get ick anymore which is very common with new arrivals. Glad it is going better
