Dead fish help

So I have a temperate tank, with fancy goldfish, cool-tolerant Corydoras, and until yesterday a shoal of 7 beautiful Rainbow Shiners. I’m aware they’re probably the most sensitive fish in that selection.

Yesterday I visited a fish shop a few kilometres away in Spain as my LFS doesn’t stock a huge range of aquarium stuff. I bought and used Tetra Crystal Water just in that tank as it’s always cloudy, but I assume from goldfish and Corys rummaging in the sand. This morning all my Rainbow Shiners were dead. Why?

Another issue I have is I have only found 2 bodies, which means there may be another 5 fish about to start rotting and releasing ammonia. So should I leave it today, hope the Corys eat their fill, then do a massive clean out and water change tomorrow? Or should I do that tonight, though I believe peak ammonia emissions happen after 36-48 hours. I’ll never use Crystal water again for sure!

How is my fish tank

Guys this is my fish tank it has 1 betta fish and 9 guppy fish and 1 molly , first i had duck weed and elodea ( waterweed) but I had exams so i was not at home and my dad cleaned my tank and yeah he threw all of that i tried to find but didn't find any of them easily so today morning my guppy died because yesterday when I came home after long time i saw that water was not clean and all . Basically no plants so the waste was all collected and i think the guppy died due to lack of oxygen like all fish where on surface level so i had no option but to add filer ajs that driftwood i already had but I put it today for first time in tank. And those guppy were like small fries which now they have grown so first i had like proper hiding space for betta and all but now I don't proper one . I am looking for betta hammock too but its only available online for 600 and all so give me suggestions and all what else i can do . Honestly if i had some another tank or something I could have shifted the guppies and molly I know how betta likes it's environment .

The second image is like last year when i originally started the tank yeah it had too much plant growth and all i learned and now no plants yeah had shrimps too they died had like 4 or something. So it's been like 4 or 5 months or more i guess to my fish tank

Advice needed for a long time fish keeper but new to goldies

Long time fish keeper (10 years keeping betta and other small fish) but first time goldfish keeper here.

I've taken in a fancy tail and a comet goldfish (freebies that I couldn't just leave behind), they were living in 20 litre tank but I've moved them into spare a 45 litre tank that I had free and added established filter media. I have a few questions:

I know the tank is too small for goldfish but realistically how long could I keep them in this setup?

How often should I do water changes in this setup to keep them healthy?

What's the best food for them?

I'm keeping an eye out for a second hand tank or even a large container pond (I have a covered patio that has space for a barrel or trough or similar) that I can eventually move them into but that could take some time in my semi rural area. Any advice would be much appreciated!

Hey guys! Does my oto look overweight?

I noticed him resting his belly on a rock, so just wondering if i should tone down the algae wafers? My tank is well established so they get a good amount of algae but i supplement with wafers and other snacks from time to time.

What should I do about this fish?

Apologies for the poor video quality. I first thought it was ich but the white spot seems to be embedded in its body, not just sitting atop it. Clearly its fin is injured too. Can this fish be saved? What do I do?

Gardneri killifish aggression

Hi guys! A couple months ago I got three Gardneri killifish—1 male, and 2 females. They live in a highly planted 20 gallon tank, and have been eating well and even reproducing. The females are confident and stay near the surface while the male likes to hide most of the time.

However I recently noticed that the females have nipped fins, and by observing I found out that it's the male chasing them.

Is that behaviour normal? Should I separate them? Would getting more females "spread the aggression" of the male?

Any advice would be appreciated, thank you!

75g stocking ideas

Hello, I'm looking for advice on what fish to put in a hypothetical 75g that I want.

I'm not a fan of tetras, but other schooling fish are fine.

I'd prefer having a centerpiece fish, to be honest. I was thinking of a good severum, so you can work with that if you'd like.

Suggest anything! Share your tanks! I need inspiration lol

Help needed

Hey guys. As the title says.. I have a flame tailed apisto which looked to have a little white spot, so I put it in a separate tank, have been adding white spot treatment and doing water changes, can’t see any more spots on the fins, but it had also started to develop a bit of a white mark near the eye.. I figured same disease but it’s eye it just getting worse. The pictures are terrible as he’s still pretty active but if someone could identify what’s going on so I can point myself toward the right treatment, it’d be much appreciated! Thanks in advance.
