What your tap nitrate reading.
is there enough aeration in the tank.
Check gills to see if there pale with excess slime or red and inflamed.
Any excess slime on the body of the fish.

 

[WILDER]

Did you overdose the med.

 

[blue130]

the tap nitrate reading is 0mg its showing ideal water conditions
ive checked over the fish there is no excess slime its hard to look behind the gils but again they are not relly pale neither red or swollen. 2 of my lighter healthy plattys seem to have darker red gills than the others but not swollen, maybe thats because they are lighter fish and slightly transparent my pump is for 150ltre tank and i guess minus the ornaments mine is 120ltre tank so i guess that shud be sufficient. ps sorry i was a while jus dun the water test.

 

[The Village Idiot]

It seems your main problem is with the livebearers. In my experience with live bearers, they do better at temperatures around 23.8. If I have temperatures approaching the 26.5, I also find them gasping at the top, hiding, and appearing generally unhealthy. I suspect this has to do with warmer water's inability to hold as high a concentration of oxygen.

 

[blue130]

i dossed the med at 8mle on days 1 2 3 4 5 as directed and done the water change on the 8th day

 

[WILDER]

If there plenty of aeration I doubt it's the temp.
I wondering if its the med.
Did they all start to die after the med was introduced to the tank.
Check the date on the med bottle.


Lost any fish that have looked thin.

 

[WILDER]

Gulping for air can be bad water quality, parasites, toxins, ph shock.

 

[blue130]

the med bottle is dated the 8th 2013 and i bought it before i treated them new. i lost a male gouarmi before and a molly b4 the gouarmi was under suspitious sircumstances as he was wedged up the side of the breeding net so in guessing he was unable to breathe. the rest have been after the guppy was rolling around on the gravel looking dissorientaded and the other molly was found dead 1 morning up a corner out of the blue with no symptoms before hand

 

[WILDER]

How many fish are flicking and rubbing.
Any fish dart around the tank, or spinning around or swimming in a jerky movement.
What does it look like when your fish go the the toilet.
It's pointing towards parasites, bacterial.

 

[blue130]

the poo looks normal most of the time except they have sum clear in with the norm in patches the healthy platy poo looked unusualy green the other day the guppy that died was rocking side to side to begin with and then deteriorated the next day the rest swim normal except the few that dont swim much or if the platy scratches against things which is once in a while say 5 times or so a night of watching them. as i say there is no phsycal marks at all on them apart from his fin being clamped a lot he looks fighting fit.

ps 2 flicking occasionally non darting or swimming funny

 

[WILDER]

Clear mucas poo can be a sign of internal parasites.
Signs of internal parasites are,
Long stringy white poo, or clear mucas poo.
Worms prutruding from the anus.
Being skinny or bloated.
Enlarged anus or red inflamed anus.
Swimming on there sides sometimes.
Bent spine sometimes.
Flicking and rubbing sometimes.

I think I would worm your fish as it's best to worm fish anyway.

are you running black carbon now to get the med out of the tank.

 

[blue130]

yes added them this morming will the wormers affect the fry? and should that solve all the probs?

ps they are not skinny or bloated and i have saw no worms petruding??? is it still the best route?

 

[WILDER]

Not sure about fry when it comes to internal worming.
You would have to do a search.
Fish shouldn't be producing mucas poo as it's a sign of internal parasites.
long stringy white poo can mean constipation, bacterial infection, internal parasites.

 

[WILDER]

Every time I bought guppys they always had internal parasites.
Do you know if they were wild caught.
