Is it possible you caused a Ammonia spike with the tank changes and the new fish being added? Rather than "normal" can you give us the numbers? We're just trying to help sort this out with you.
I completely redid my tank. It was soil-based before and it was giving me problems so I took out all of the soil, washed out the tank, and replaced the soil with gravel. During this time I kept my filter in a bucket of tank water, and started running the filter again
after I was finished. I kept an eye on water params for the first few days and they were normal- meaning Ammonia 0 and Nitrite 0 I tested again yesterday just in case and they are the same. My testing kit doesn't come with a test for nitrate.
This was a month ago, though. everything was fine until I bought the Platies a week later. the
first one died a week later, and then the other 2 died within the next week. A few days went by until my other fish started dying. If the Platies caused an ammonia spike it wouldn't have caused my other fish to start dying 3 weeks later especially since ammonia and nitrites are 0.
I noticed last night that one of my remaining Platies has stringy poop, which is a sign of internal parasites, right?

I really don't quite understand why they sell incomplete kits. There are 3 stages to the Ammonia cycle as you know but it can take up to 6-8 weeks. Being able to actually see a NitrAte reading is good to have! But without doing any water changes along the way, you haven't diluted down high numbers if you had them. Putting your filter onto a bucket is good. Hopefully you didn't change the pads in it, or it wasn't sitting for more than 24 hours. Still some pretty big changes plus adding new fish before the bacteria can catch up to the bio load. It's possible that in one month you are not yet thru a new cycle and could account for the older fish also being affected.

I can't advise on the disease side at all I'm afraid. Hopefully someone can chime in here.

There are really only 2 possibilities here The first is the fish are being poisoned by water quality issues or second there was a pathogen introduced into the aquarium by the unquarantined livestock. Identifying the pathogen without see the livestock is not possible but I would be leaning to a water quality issue of some kind.

Can you do some 50% water changes daily for the next week and see if things quiet down? Don't add anything new to this tank for a month. And try to confirm exactly where you are in the cycle. Get that other test kit you need.

Thanks, everyone. I assumed it was disease because it started with the new platies, but I wasn't thinking about other water quality issues besides ammonia and nitrites. I will do some water changes and keep you all updated.

My guess is that if it's water issues then it will settle quickly if you keep up and keep things diluted. If it's disease it will continue.

There is an old saying that nothing good happens "quickly" in a tank. And thinking over what changes you made, you did a lot of big changes. Think "s...l...o...w..." when making changes. You might have been ok if you hadn't added the newbies, but with the tank overhaul all the new gravel is "new" and has no good bacteria yet to support newbies (and you added 5?). So basically you are running the old bio load of existing fish on just filter nitrAtes and I'm assuming you put the live plants back in? If not, those would have been taking up new ammonia too right and might not be there any more? I'm making an assumption because of the soil. Also remember too that topping up water does not dilute the minerals/etc that are intensifying. The water evaporates but the minerals don't and next water change we add new water with more minerals.

Wishing you nothing but good luck and improvement!!

Yes, I did add all of my live plants back into the tank.
I'll start tonight with water changes. It's very time consuming since I can't use a water changer (I don't have the right type of faucets), so I have to go back and forth with buckets, -__-

I agree that waterchanges are the best course of action. Nitrate poisoning affects fish slowly, compared to nitrite and ammonia, but it is just as fatal. If you have 0 nitrites and ammonia and have gone a month without water change in a stocked tank, then you MUST have high nitrates. The ammonia from bioload has to go somewhere usualy ends up as accumulation of nitrate.

Oh... I still use buckets for my tanks too. Its hard work, but its a labor of love!
Please keep us posted with updates and test results, were pulling for you!
Your live plants will help keep nitrates down a little, but imho water change each 1-2 weeks is essential.
Best of luck to you and your pets.

If anyone would like an update, I did partial water changes every day since I posted and now I'm on day 3 and counting of having no dead fish!
I lost half of my fish, though. I'm down to 3 zebra danios from 6, I'm down to 7 serpae tetra from 14, 3 Platies out of 6, but thank goodness my cories, ottos, and shrimp weren't affected.
Thanks, everyone!
