Albino heckli in problem

[Aalok bairwa]

Yesterday bought a albino heckli for my 5 feet tank , at night it was good and moving freely , but today when I watched my tank I saw my red eye tetras are nibbing on my albino heckli,, it seems like they were eating it alive i immediately removed it from there and shifted it to my planted tank and used drip acclimatation.

I told this to the shop owner from where I got my buddy they said just increase the temperature and add some anti ich ,, and stress relifer , then I went to my nearest aquarium shop and show the video how is the fish so he suggested to put half - half caps of these medicines.

I done all of them ,, my temperature is settled to 26 and sponge filter is running and added those medicines too , also I yesterday done the water change so no worry of ammonia.
Should I wait for 2-3 days so that medicine works

But guys I don't know why it also go upside down ( like it got swimbladder ) not sure about that but rn i always found it upside down then I again stable it with my net but after some time again and it still breathing ,

Should I leave him upside down and let it to stable itself after few days

If you guys can help me to save my new buddy that will be too helpful

Medicine that I used ,, I know the medicine is strong but I told that same to shop's uncle but they told me it was attacked by old fishes and gone in stress that why you can see red spot on body ,, btw I went aquarium shop for aquarium salt and stress relief but uncle told me to use this ,, he told that he saved many fishes with these symptoms

Seems like it’s just stressed out and didn’t acclimate well. Good chance it won’t make it IMO. Would keep the fish upright. Add some salt 1 tsp per g. Avoid stress don’t think meds will help. Check your water parameters.can add some seachem prime or safe if water is off.

Water parameters are setted for geophagous requirements like soft water , low ph ,, ammonia and nitrates not present as done water changes yesterday and there are lots of plants too rn I make him to be stable my pushing towards back glass and plants also helping it too hold btw if I just leave it for few days with its proper requirement will it get revived and gets healthy
