Fish Dying...

[VermillionPrism]

Hi, lately, my fishes are dying slowy, one by one... It started when i added 4 threadfin rainbowfish into the tank. My tank consist of 5 swords, 1 corycat, and 2 guppies in 10 gallon. I was planning to add them to my bigger tank, but with this happening, i'd like to know what is happening first. So basically when i added the threadfin rainbows, i noticed one of them has white spot, so i added coppersafe to my water to treat it. Everything was fine until a few days later, when some of my fishes has clump fins, 1 of my sword died and a next one follows in a few days. Yesterday another of my sword died. and today my guppy doesnt look too well, with bloated body. My rainbows are fine, and the water parameter are all in the save-zone. Does anyone know whats wrong with my fishes? maybe there was some kind of disease on my rainbows when i added them onto the tank? Maybe some paradise infection? or are the white spot killing my fishes (btw, the white spot isnt visible anymore, but my tank is still in medication)? if anyone knows a solution, that would be great. And yea, i ve been changing 20 percent of water every 3 days.

Thank you.

Have you increase aeration with the high temp and med.
Parasites can cause bacterial infections on top.
Can you post your water stats.

All the water stats are in 0
i raised temperature, and what do you mean by increasing aeration?
Are there any ways to tell what is parasite and bacteria for dieases that can be seen? thank you again.

Aeration where you have an airstone to create more bubbles so the fish can breath in high temps with meds.
Does your filter turn up and down for the water flow.

What is your Ph level at?

if all your stats are at 0 there is a problem...How are you checking them and what are you checking for ?
it could be cycling if they are all 0

i dont know, my stats are just at 0 o.0, maybe i need a new kit or something. I am just checking for ammonia, nitrate, nitrite, and PH. Ph is around 7.5.

Oh yea, another question, one of my fish has a red spot near its head, is that bacterial infection or parasite, i dont really know how to tell the differences... Thank You again.

Red spots are usually bacterial yes.
Does it have any white around in the edge of the spot.
