Please Help me! All my fish are dying

[Joegourami]

Suddenly in my 40 gallon tank all my fish are dying with no reason. I tested for ammonia, nitrite, nitrate and chlorine and everything is in the safe range. Please give me some advice on what could be happening?

That is the weird thing, they all look an eat normally, the last fish I added were some neons on sunday, now 16 fish have died. Only that 1 day before dying they look dizzy and suddenly die.

 

[bob mccoy]

is it mostly the neons dying

Well they were the first dead, I thought the angels ate them. But then other fish were dead too. Penguin tetras, lemon tetras, angels and neons

im guessing the neon's hosted a parasite. are u doing scheduled water changes weekly. if all parameters are checking out and heat is ok and ph is good I would treat for internal bugs. imo.

 

[Joegourami]

I do 25% every 2 weeks. What can I give them for the parasites?

Also another detail. One fish was pooping green stuff that the filters never could catch.

i would use a med called focus. it can also be added to flake food . seachem.com carys a product called paraguard that i use a lot when qt fish in a tank when i buy them. im guessing the green poop is algae.

What do you mean by 'safe range'?
What are the numbers?

Focus is the thing that binds medication to food- it's not a medication itself

NH3: 0.0 ppm
NO2: 0.0 ppm
NO3: 5 ppm
Chlorine: 0 ppm
pH: 6.5

A parasite wouldn't kill that quickly. There has to be some sort of toxin in the water- have any air fresheners or pesticides been sprayed nearby? Any new rocks, wood, ornaments etc?

What are the symptoms of the fish that die, and how quickly do they succumb?

Well the public fumigation van has been passing by my home these days, and the main door is like 2 meters from the tank. The only symptoms that I've seen are total loss of motion control (swimming upside down, frenetically or not swimming at all).

That's the problem. Your water is probably toxic. 25% every 2 weeks is not a water change. Do 50% a week.

Tell me the kind of toxin or how to remove it.

Even though that isn't very significant... Why try to fix something which isn't broken? The parameters are normal for a cycled tank. You could bump up the water changes but the levels are fine without it. If the tank has been working okay for a while like that, then I doubt it's the lack of water changes

I would start by adding lots of carbon to your filter and change it every week. Also the 50% weekly water changes should do a lot of good. Also try to get something to seal off the bottom of your door where the fumigation chemicals are getting in. This should help. Good luck!

Will purigen work instead of carbon? I currently have purigen in my filter.
