Guys I am having a problem and need some help.

I've lost 3 fish recently after buying a trade in fish from the local fish store. I should have never bought him but did he didn't last a full day started to float and then died. was clearly ruff.

next fish was a rafael cat I have had for years, got sort of a white ting to him and one of his fins bones had become exposed. died friday.

next fish was a small flag tail maybe 3 inches had 6-7 ich like spots on him, was fine last night was swimming this morning and was dead by lunch.

ive added salt and brought the temp up, I also got some ich attack and pimaflix, I was using the pimaflix becuase my red tail giant gourami had a whiteish tuft on her tail just a circle about 2 milimeters I am 4 days into that treatment.

This is a well established tank 55 gallons with a few year old magnum 250 and now a 24hour old aquaclear 110 with extra sponges from my aquaclear 20.

Occasionally the fish are up by the surface or almost laying down but for the most part have seemed fine except for rubbing several times an hour(everyone but my endli). then they just drop dead.

I had my water tested after the first one, got a reading of 70ppm nitrate and nothing else. I've done a 25% water change I also have suspended feeding.

residents are 9-10inch blood parrot 6-7inch red tail GG. 4 inch endli 2 4 inch tin foil barbs and 2 featherfin cats one 3 inches one about 5. Any idea's ?
 
more water changes nitrates are extremely high
 
do like 50% wc or do 25% everyday.. i dink ur tank crash by addin that new fish and it proably had a disease or was sick and affect all ur tank mate
 
50% change we will see what happens.
 
With nitrates over 20ppm, the immune systems of fish is reduced. The higher the nitrates and the longer the exposure to the elevated nitrates the weaker the immune system. White blood cell production comes to a screeching halt with high nitrates.

Lots of massive water changes are going to bring your nitrates down. Weekly 50% changes are going to keep them down. It takes about 5 weeks before the while blood cells start appearing in the blood serum again after the nitrates are down around 10ppm.

You have allowed your fish to live in water with elevated nitrates until they were defenseless against any germs, then you added a fish that hadn't been quarantined to that tank. Its introducing an illness to the already fragile system is not something to be surprised about.


Good luck.

Please learn 2 important things from this mistake:
1.) weekly 50% water changes are required to maintain water quality.
2.) All new fish need to be quarantined for 5-6 weeks before getting added to an established tank.
