Help My Fish Are All Sick

[leepeggymitchell]

All my fish are dying Help!! I've had a tropical fish tank for 2 months which i got off a friend, everything was fine until about 1 week ago when i noticed white spots on my Pacu fish. I brough white spot treatment from my local fish store but it hasn't worked and now all the fish have got it and are now dying. so far 7 fish have died and i don't know what else to do! Could anyone give me an advice before the rest die?
Thanks

Need lots of info on size of tank in gallons or litres, full fish stock of how many and which kind, water stats in ammonia,nitrite,nitrate, and ph, have you turned temp up if so how high, also have you added salt because some fish types can't tolerate it, finally have you added extra aeration as high temps and meds reduces 02 in the water.

I'm new to fish keeping so that it easy on me thanks!
It's approx 13 gallons. 4 Albino cory, 1 featherfin catfish, 1 glass catfish, 4 pacu, 2 butterflyfish, there are also another large Catfish and 2 fish that look like a bit like gold fish. (i'm not sure what they are because they all came with the tank)
Ammonia level:1
Nitrite: 0.50
Ph: 7.2
Temp:24.5
I haven't added any salt

Most likely some of the deaths are down to new tank syndrome, heres a link on treating/avoiding it;

Do the spots on the fish look like this;

or more like this;

?

Well overstocked for that size tank, the pacu grows massive and i would advise taking them back to the lfs.
You have a nitrite reading so i would do a water change, you might lose a lot more fish as that's a high nitrite reading, as the tank is well overstocked, i would turn temp up to 30 but only if you have an airstone.

I not sure if i got the size right. the tank is 1.2m long 430mm high and 400mm deep. I done a 40% water change 2 days ago but since then 3 fish have died. could this cause a high ammonia reading?

 

[Tokis-Phoenix]

Did you use dechlorinator when you did the water change?

 

[WILDER]

Yes reading that high dosn't take long to kill fish, when you use fish for cycling a tank it stresses them takes it toll, then the immune system can shut down causing desease, a fish has to go through the ammonia build up then the nitrite build up, no wonder most of them don't make it.
see how many gallons your tank is here.

but i'm using medication doesn't that give a high reading?

 

[WILDER]

No, it shoudn't hardly touch your water stats, what med are you using.

That's ok then, methylene blue can alter water stats, plus not very good at treating whitespot in my opion, but that med should be ok, plus it should tell you in the instructions.

i've just done a 40% water change and put the temp up to 30! Thanks for all the help wilder and others. Lets hope the info i've followed helps. If it don't i might change to just get 1 gold fish
