I'm in dire need of advice on how to rescue my roommates Betta. This fish has been suffering since I moved in at the start of September, and it has gotten way worse since I confronted my roommate about it at the start of November. Right now he is on vacation and wont be back for another week and a half, and after returning home today to see the state of the tank I've decided enough is enough. So here is the complicated situation....
The water hadn't been changed since I changed it for him at the start of November (he says he will change it but never does, also has refused my help before but I hate to see the poor thing suffer especially when my roommate isn't here). He keeps the fish beside a window away from a heating vent (not good in Canadian winters!) in a 24 hour constantly lit room. My roommate went away two weeks ago a couple days after I left our student house and I came back today to find that he dumped a bunch of food in the tank to make up for regular feedings. Algae had grown through the tank and water was distinctly brown and around 35% opaque. Food and waste were rotting in the bottom of the tank. Needless to say I did a 100% water change, scrubbed down the tank and gave his fish new clean gravel. Also have moved the fish into my room away from the window where he will have has proper lighting intervals and regulated heat. Anyways please help me try to rescue this betta, he is in terrible condition!!!!

What type of food do you feed your betta fish? Aqueon Betta Food (though I have Wardley pellets and Nutrafin bloodworms if you think it would be better)
How often do you feed your betta fish? Im not sure but 20+ rotting pellets were visible on bottom of tank

Symptoms and Treatment
How has your betta fish's appearance changed? Clamped Fins, extremely short and thin dorsal fin (1-1.5 cm long maybe), dull coloration, entire body bloated or maybe just fat from over feeding
How has your betta fish's behavour changed? EXTREMELY lethargic, sits either at the bottom of the tank or at the top facing the corner, does not swim around at all
When did you start noticing the symptoms? He's always been in bad condition since I moved to this house in September. My other roommate who moved out told me the fish had been abandoned by a previous tenant so when she moved at the start of november I took the betta and put him in a heated/filtered/clean 3Gal which I bought specifically to rescue him. All to be told by another roommate that it was actually his family's fish and he wanted it back no if ands of butts even though I told him he was sick and needed a bigger tanků as such he got put back in his 1 gal with an 100% water change. It is apparent my roommate has done nothing to help this fish since despite me asking him to multiple times in nov/dec.
Have you started treating your fish? If so, how? Cleaned tank, water change, stress coat, brought him to my room so that temp and lighting is regulated
Does your fish have any history of being ill? Not sure but always in dirty water, dull coloration and lethargic since I've moved in.
Please understand my situation, I do not know my roommate personally, and have had words with him several times since I found out it was his fish after I tried to rescue it the first time. He's been very adament that he will not give me the fish, but I can't watch the poor thing suffer like this, its sick and twisted. So please, I would really appreciate any advice.
