replace fish?

How long were the other neons in there dead before you pulled them out? If it was several hours, that might have been enough to cause an ammonia spike hard enough to kill the third neon. If you tested the water a while after removing all of them, the tank might have had enough time to stabilize again.

And what exactly is "the whirly thing"?
 
the "whirly" thing is like the fish can't control himself and he just keeps whirling around and around, drifting around the tank... until he sticks onto the filter.


i don't know how long they were dead, i just woke up and found one dead, then when i looked again a day later, I found 1 dead...
 
Cait...calm down...you always get to hyper when you post and want instaneous answers and solutions.

You are relatively new to fishkeeping and having lots of posts going on at the same time, just confuses people who are trying to help.

You are worried about fish dying and didn't even mention your heater issues or your tank parameters.
 
err i posted my tank params
and my heater's gonna get replaced. it's going up and down in the 78's, nothing more, nothing less

*ahem* obviously.

if it wasn't, why would i still have fish in my sig?

Ammonia, nitrite 0 (duh!)

nitrate is kept below 10

i know about the pleco but right now, but he's the most helpful (and he's cleaning my snail shell too lol)...

I have something similar happening in my 55g this past week. Introduced 6 black neons and I am down to 2, and my prize angel is dead. No signs of any illness at all. Just sudden death. From perfect health to death overnight. And this is in a well-established tank that is far from overstocked, with all water conditions absolutely perfect. I have thirty years experience in this hobby and I have been keeping perfectly healthy tanks with happy fish who live for many years.

But I was stupid because I didn't have QT facilities available and being as though the LFS where I got these fish has never sold me anyone with any hint of disease I figured it was okay to risk it. Maybe it was, maybe it wasn't.

So what am I saying? I'm saying that I believe sometimes there are just little viruses or unnoticed nasties which cause no symptoms and simply kill your fish. Fish are one of those creatures prone to sudden death. When was the last time a new fish was added and was it QTed for two weeks or so before being introduced?

But if you say there was bullying I might suspect that is the cause here. And/or if there is disease present, the other fish nibbling on the dead one is never a good thing. What I would do Cait is just wait for a while. You might never know what caused this, but it could have been just a quirk or something worse. Let the tank be as it is, see if you don't lose any more fish for a few weeks and if not, start replacing the fish. Whatever it was would have passed by then. Your biofilter can handle the addition of a few new tiny people at a time if it's well-established.

Well--I would absolutely hesitate about replacing neons right away--because whatever killed the others might catch any new guys. Plus the possiblity of bringing something in with the fish.

It is true that some fish are weaker when you get them from the store--bringing illnesses or other physical problems. However, you didn't mention how long you'd had your fish. I'd possit that the whirling thing and paleness could be neon-tetra disease--which is really bad. Of course it could be something else, but I wouldn't want to risk other fish.

My brother got fish on tuesday night, and one died wednesday morning. He felt really bad that he'd done something, but at that point he'd done all that he could, and sometimes fish die. But he is trying to figure out what went wrong before getting more fish.
 
In your OP, you did not post the parameters; not until 3 hrs later.

In your heater thread..

http://www.aquariacentral.com/forums/showthread.php?t=87972

you mention temp swings of 8 degrees. In a short period of time, that's all it takes.

You also need to get a resemblence of control over the slightly abrupt comments you are adding next to your answers, please.
 
well i sorta fixed it..

i set it on a steady 77 but that's all.

oh well...

77 is good for the stuff in my sig, yes or no?

my neons are living for over 3 days now... new record since my last LFS i bought neons from, the neons died in like, 2 days.

soo... my neon is starting to get aggressive because of the small numbers i think. that's why i'm asking to replace. if I do, then the numbers go up to 7...
 
78-80 is where I keep my tanks.

Anyway, wait for a while. One thing I can say is that newly acquired tetras do tend to die rather sudden deaths quite often. It's a combination of acclimation, overall stock quality from LFS to LFS, how they are cared for etc.

So wait at least another week. Then start replacing them slowly. Try to utilize a QT tank if you can.

Again, neons are rather weak fish. Almost everyone I know who has been at this hobby for a long time knows how quickly you can lose a few here and there. It's just a matter of getting the best stock, well established, and then you can just sit back and enjoy.
