Guppy help, sick fish!

[AnotherZephyr]

Hi there, I’m new to the forum and was hoping this expansive knowledge base could help me out. I have been having some issues with my guppy’s I have gotten recently. I got 1 male and 3 females from a local pet store 2 of the females were pregnant when purchased. They share a tank with a dwarf flame gourami and seem to get on quite well. Yesterday after about a week of having the guppy’s the male and females were eating and swimming normally when I checked them about an hour later the male and the 1 guppy female that wasn’t pregnant were struggling to swim upright and were flopping around in the water. I separated them into my hospital tank as soon as I noticed but unfortunately within half an hour both had passed. I did a quick examination after this out of the water and neither showed any immediate signs of disease or sickness. Although I may have missed something or it may have been more subtle that what I looked for. But the 2 pregnant females seem to be ok at this point 1 actually gave birth to its fry which I have in a seperate tank and the other is somewhat close to labor too. But when I separated my still pregnant female into the breeder box / tank I noticed it has a sort of dry looking scale strip down one side just before the tail with a couple red dots on it. Pics included for reference

Any idea why this is happening? I do know the next closest store in this chain is currently having issues with their guppy’s and not selling them due to treating them. For what I do not know though. My gourami seems happy enough and the other female that gave birth isn’t showing the same symptoms. Any advice and any treatment ideas? Thanks for your help and let me know if you need to know any more details about tanks or levels of the water etc etc.

Welcome to the forum...is the tank cycled?...see here: https://www.fishforums.net/threads/cycling-your-new-fresh-water-tank-read-this-first.421488/

Thank you, the tank it was first put in has been cycling for a few weeks but i believe the process isn't complete, the hospital tank is cycled though as it was already established.

You are welcome....follow the fish-in cycling instructions closely, use a liquid test kit (https://apifishcare.com/product/freshwater-master-test-kit), and Seachem Prime for your water conditioner.

Hello and welcome to the forum!

It looks like an injury to me. (Something/it scrapped against something and it punctured them dragged down)

Do you have any sharp decor? What kind of filter do you have?

Clean water will heal that quickly. 65%+ daily for the next week or until it clears up.

nothing sharp i can see mainly soft fake plants and rounded rocks / decorations and has been friendly with other fish as far as i can see.

The bottom 2 pictures, the fish has a bacterial infection on its back.

Wipe the inside of the glass down with a clean fish sponge.

Do a 75% water change and gravel clean the substrate. The water changes and gravel cleaning will reduce the number of disease organisms in the water and provide a cleaner environment for the fish to recover in. It also removes a lot of the gunk and this means any medication can work on treating the fish instead of being wasted killing the pathogens in the gunk.
Make sure any new water is free of chlorine/ chloramine before it is added to the tank.

Clean the filter if it hasn't been done in the last 2 weeks. However, if the filter is less than 6 weeks old, do not clean it. Wash the filter materials/ media in a bucket of tank water and re-use them. Tip the bucket of dirty water on the garden/ lawn. Cleaning the filter means less gunk and cleaner water with fewer pathogens.

Increase surface turbulence/ aeration when using salt or medications because they reduce the dissolved oxygen in the water.

Add some salt. Add 2 heaped tablespoons of rock salt for every 20 litres of water. Keep salt in the tank for 2-4 weeks.
If there's no improvement after a couple of days of salt, look for a broad spectrum medication that treats fungus, bacteria and protozoan infections in fish.

---------------------
It probably has intestinal worms, as shown by the stringy white poop. See section 3 of the following link.

What to do if your fish has Stringy White Poop.

Fish do a stringy white poop for several reasons. 1) Internal Bacterial Infections causes the fish to stop eating, swell up like a balloon, breath heavily at the surface or near a filter outlet, do stringy white poop, and die within 24-48 hours of showing these symptoms. This cannot normally be...
