Please help, my silver Molly is upside down at the bottom of the tank but he is still breathing.

I don't know what's happened. My ammonia and nitrite are both 0 and my nitrates are under 40 so I don't know how this has happened, please see picture

Hi fishtank—

As we explained in your first post, the fish has suffered ammonia poisoning, and is showing the effects of it.

You explained that you had had high ammonia in the past, and we explained that this is what has poisoned your fish. The only thing you can do now is to keep the tank conditions absolutely pristine. The problem is that past poisoning will likely affect a fish in the future, and compromise its long-term health. This is just a sad fact of fish (or any) life.

Have you done a recent water change? I'd asked you how large the tank is, and how many / what type of other fish you have. Could you tell me? There is little to be done for this fish now—it will die, or it will not—but I am concerned for other fish in the tank.

If you give us information, we can help.

Abs.

Hello, apologies for posting twice, I initially done the first one but my Internet crashed so I thought it didn't post so I made another one

My tank is 60 litres

I have the following in my tank

4 tetras
1 platy
4 mollies
1 angelfish

3 of the tetras, 1 of the mollies and the angelfish were all in the tank when the ammonia was high.i got the ammonia tested in a shop so not sure how high it was but my nitrite was a very dark purple so that was very high. I made water changes everyday and sorted it all out about a week ago.

The last water change I done was Friday. Tested the water yesterday and its all fine. I'm really gutted that the tank went bad, cos I get really attached to my fish. Just hope the other fish that were in the tank when it was bad will be ok.

I am currently cycling a 240litre tank so hopefully in the next week or two they will all have a new home and have a lot more space.

Thanks for the replies and hope to hear back from you soon

Ok. Don't worry about the double post—it's just that it makes it hard for us to help you, and pushes other new posts down the list.

So, your tank is over capacity, which I had thought might be the case. You are at 112% stocking capacity, and your filtration is almost certainly insufficient.

What were the exact parameters (numbers) when you tested your water yesterday? You said 0 /0 / 40. Is that correct? Which test did you use?

Because several of your fish were compromised by the tank poisoning, I would be doing water changes every other day now, with Prime added with each change, in order to keep ammonia levels at absolutely 0.

Once your new tank is fully cycled, they will be much happier there, though if you tetras are neons they may at some point become angelfish food.

Good luck. Clean water is your best medicine at this point.

Yeah def nitrite and ammonia is 0 , the water is clear after testing it. I'd say nitrate is between 20-30

Do I still need to get prime even though my ammonia is 0 and has been for over a week?

Thanks for the help abs

I think it's a good thing, but if you keep up on partial daily changes (even just 10%) and test daily, that should be good.

I really hope this guy makes it, but even if he doesn't, pristine water will help the others.

If he doesn't make it, then go back to weekly changes and frequent testing. But fingers crossed that he'll pull through.
