Guppy sick with scales sticking out and trouble with buoyancy

Hi, so his scales have been sticking out since a few days ago, I checked water parameters cause I thought it could be dropsy. Water parameters are
ammonia = 0
nitrite = 0
nitrate = 5ppm
pH = 7.4
so I don’t know what’s wrong with him. its like his stomach keeps floating unless he errects himself and just swims around messy like, like he cant move properly. He looks dead in the photo but isn’t and the second photo is him forcing himself to stay upright. Anyone know what it is and how I can help him? I know if it’s dropsy theres nothing I can do . But how do they get it if the waters good?

 

Velvet?????

 

Velvet?????

I don’t really think it’s velvet as he‘s not showing most of the symptoms, it seems more like he’s half paralysed from tail down and can’t lay or swim normally, like pushing his way around using just his front fins

 

Maybe it could be multiple diseases in one? Dropsy and some kind of paralysis disease?

Yeah possibly, unfortunately he has died but now my other white guppy is also started to show the same symptoms. I got them together and they were happy and would chase each other in a playful way, until I added melafix to treat another guppy with fin rot who unfortunately died. But after the melafix and pimafix they were never the same, they barely showed interest in food or anything. I got 4 new guppies in the quarantine tank and they were so active and full of life it was a shock. they never really got that much more active even after I added the new ones. I’m worried, I hope that the newer ones don’t show it cause then I’m gonna suspect it’s something wrong with the tank water and not the fish. I’m so confused

side note I did just finish two weeks of treating for internal parasites cause I thought they looked quite thin, they started to fill out and then this happened. So it cant be parasites surely. I have done 50% water changes every week cause of the meds, so the water is quite clean ... I thought

You do have a test kit ? I’m thinking maybe it was too many meds. Sometimes it’s hard to figure what our fish have so we medicate and then medicate more and it ends up being just too much. They are tiny little guys after all. Your heart is in the right place good luck with your babies and make certain the water is pristine. It can make all the difference. Have you tried a small amount of salt? It helps with many things in the right amounts...
