Corydoras wont stop dying

Where's your test tubes?

I looked and it says only chlorine couldn't find anything about chloramines for my city.

I also just tested the tap and it says 0 ammonia!

OK. Both can be sources for ammonia, so best to know. If you have live plants, especially floating plants that are obviously growing (as opposed to failing and dying), I would not fuss over ammonia testing at 0.25, unless it increases.

Had to do a small edit, let's keep it family-friendly, please and thank you

How are those corys doing? Still floating and gasping after a WC?

My bad lol! Sorry

But nope they're not going to the surface at all anymore.

No problem.

Good to hear about the cats...now they're getting the fresh, clean, treated water they like

I dropped them a few months ago

I had duck weed but it got stuck to the rims, glass, or sucked into the filter so I gave up on it. I have no idea what the plants are in my tank except the Java moss.

Broken API test tubes is another reason I favour alternatives to API lol

 

[Avel1896]

Test drops ? So should be accurate.

I had most then one by one they would roll and break

Ooops

You can buy replacements on Amazon....you need to be sure you are testing the right amount of water

Duckweed is a help, but more substantial plants are better. Water Sprite, Frogbit, Water Lettuce.

Sooo I'm really starting to get frustrated. I had 9 panda Cory's, 6 peppered corys, and 6 bronze corys. I'm left 5 bronze and 1 peppered Cory. Well I got 5 new peppered corys and now one of my bronze corys died. So peppered corys and 4 bronze at the moment.

They eat a very big range of foods, blood worms, veggies, flakes, egg, etc.

The water parameters are

Ammonia 0
Nitrite 0
Nitrate 10
Ph 7.6
Water hardness 7

They're all extremely active and healthy, as well as eating a ton. Until I just wake up and they're dead. There's no parasites or illness either.

It's a planted tank as well

Temp is 73

Gravel and rock for substrate

I really have no clue what is going on. And it's only the corydoras dying, literally all of my other fish are fine and I had my corys for about a year now and got them all pretty young.

Other tank mates, 1 kuhli loach, 2 rainbow sharks that don't touch the corys at all, 2 red bristlenose plecos that are still young and don't go near the corys unless eating but they eat algae wafers or stems, while the corys eat the smaller bits, and now I have 4 cherry barbs who are juveniles. As well as a bunch if baby snails. They've been dying way before the cherry barbs or snails came into the tank. Their bodies when dead have no marks on them either.

I may have missed this information in your previous posts so forgive me if this is redundant but how long have you had the fish that are dying in that tank? And if they are new, how did you acclimate them? I ask because it almost sounds as if they suffered PH shock or ammonia shock while acclimating. As I said, if this has already been answered and evaluated, just ignore me!

I may have missed this so please forgive me if this is redundant but are the dying fish new additions? I ask because there's a possibility they've suffered PH shock or ammonia shock from when you acclimated them to your tank. I recently had a similar situation when I bought fishes from a source with a vastly different PH than mine and acclimation went poorly to say the least (50% mortality). As I said, I may have missed this in this discussion so if this is irrelevant to your situation, please just ignore me!

Some new ones died bust mostly fish that have been in the tank for over a year. I'm guessing probably the ammonia since it was so high at the point I put them in the tank (I'm guessing) they died probably as well as chlorine

Are any of these high maintenance plants? At the moment I don't do fertilizer or c02 doses but my plants have been growing like crazy since I got them. They were only 4 small stems when I got them not they have like 6 sprouts on each which I have been trimming and replanting to make more!

I do really like the water Sprite as well as the frog bit
