Okay so to start. I had a 20 gallon tank that had 1 beta 2 cory cats and 1 turquoise rainbow fish. The tank sat that way from January ish to about a couple weeks ago. I then added 2 dwarf rainbows 2 boesemani rainbows and 2 more female betas. Everything seemed fine then I eventually noticed that one of the boesemani was definitely a boy and the other a girl. The big male turquoise was being darted at by the tiny boesemani i assume for male dominance. Then one morning i woke up and my big male turquoise had turned an all grey black color so I panicked removes him and put him in a small observing tank. Once i did that his colors started coming back and he seemed okay so i figured probably stressed out and tried to hide itself to look like less of a threat to the aggressor. Well i removed the small male boes. And got a female and 3 Australian Rainbows (1 non aggressive male and 2 females) then i noticed the turquoise who had never seemed anything but a chill swimmer was randomly not attacking but jumping in the direction of other fish i assume to get away from him so he could have his space. So i got and set up a 55 gallon tank moved everything over. now today is the first day after moving to new tank, and i dont know if this was there before i dont think so but he seems to have a crook/bend in his tail now as well colors were darker when i got up (charcoal tail and dark/faded color) he ligjtened up a bit but not to normal id say. He still eats but not like he used to (darting to the top to grab food) now he just kinda waits for food to fall and grabs it. No fast swimming just listing lazely around similar to a beta. Prior tank was a 20 gallon but everything else in ther was baby sized so the tank was adequate for the time but i was going to upgrade anyway and i care deeply for my fish so i wanted to make him happy and get a new bigger tank. He is now isolated in the 20 gallon by himself incase it’s some type of disease or injury that can lead to anything as i am very new and dont know much first hand but read alot. So thats the back story water Parameters are ph 8-8.2 amonia is usually 0 but at .25 ish ppm because of new fish. Nitrite 0ppm Nitrate is between 5ppm and 10ppm and i will attatch some pictures thank you in advance to anyone who can shed any light or offer advice.

Fish TB comes to mind, given the curved spine, strange lesions, and lethargic behavior.

I'm still seeing a lot of similarities to fish TB. Here's a video you might find helpful.

Fish TB as mentioned is a possibility or some other bacterial disease. The bacteria responsible for it and other diseases such as columnaris are present in many of our fish. Most of the time they are latent and held in check by the immune system. Periods of stress can cause outbreaks and some species are more prone to outbreaks of Fish TB than others including rainbowfish, guppies and labyrinth fish such as gouramis and bettas. This guy has been subject to a fair bit of stress judging by your first post. In fact just being a lone individual of his species (for a schooling fish) is stressful in itself. Unfortunately I don’t think that there’s much that you can do for him now.

Well it sucks because he was my second ever fish and he was just all by himself full grown at petco so i wanted to give him a good home but i couldnt find any turquoise rainbows around here to save my life so i had ordered a couple off aquariumfish.net and literally the day i had to pull him from the 55 was the day they came. This whole COVID-19 set me back. I was trying to give him some friends and get a some rainbows i could get around here for the time being (i asked the lady at the fish store and she told me it would be fine. Well it wasnt......

now he is in the 20 gallon tank in iso with a salt bath of 5Tbs for the 20 gallons and praying he’s a fighter. I also treated the big tank with aquarium salt as a preventative for them.

I even called a vet and he is consulting with other aquatic doctors to try and make a diagnosis for sure. I figured from what i saw the salt will atleast give him a boost enough to hopefully eat again and then find out if there are any specific treatments to do.

Great. Positive diagnosis of Fish TB is generally determined by necropsy where they identify the granulomas on internal organs, but let us know what they think.

Says fog on body is excess mucus because he’s stressed. I mostly listened to this one except kept male rainbow in iso and the 55 as is but treated both with aquarium fresh water salt.
