whats wrong with my betta?
Hello, I need some advice on how to help my betta, Balloon. On Saturday we moved from upstate NY to NYC, on my way out of my dorm I forgot the final bag I was supposed to take with tank water (not great, I know, honest mistake). I left about 2gals in the tank and covered it with a trash bag for the drive, I added (guessing) about 4 more gallons to the tank when I got here. He went in the tank in the morning when the water was settled. He seemed okay at first but now 4 days later he isn't as active, and his fins look slightly clamped but im not sure. He's moving around (not as much, hes at the bottom a bit which isnt typical (hes usually very active or on a plant near the top of the tank) and not refusing food. I noticed him swimming a bit on his side too, he has a small bulge at the back of his tail that I'm not sure what it is as well (circled photo). My tank also developed a film at the top, I removed what was there however I can tell there are small amounts of it on the substrate. Google said biofilm and harmless but its not typical or like anything I've experienced, but it might be worth mentioning. First picture is from just now, the others were 2 days ago.
Info that might help or be relevant:
Tank: 10gal (filled to about 6 rn), sponge filter with adjusted airflow
Age: About 6-8 months
Breed: halfmoon (he is from petsmart, I do not support them and please dont buy fish from there)
Temperature: 72-74° (new heater coming today so I can make that 78-80, currently there are two 25w in opposite sides of the tank)
Products: I use seachem prime (I have stability and flourish as well but neither have been used in a few weeks), fluval stratum, morpani wood, fluval bug bites (abt 8-10 pieces a day), omega one bloodworms (he hasn't had one of these since before the move). I have Kanaplex on hand and I used it previously for him when he had fin rot about 2 months ago, 3 doses.
There are no other fish in the tank.
Parameters:
Gh- 60 (typically 120, before the move)
Kh- 0 (typically 40 before)
Ph- 6.5 (typically 7 before)
Nitrite- 0
Nitrate- 20 (I know this should be 0, but I wanted to ask for advice before doing anything to the tank)
*This is from an API test strip, the tank water bag sadly also contained my master kit so I'm using my back-up while I wait a week (soonest I could deliver) for another API kit.
Please note that any and all advice is welcome and I just want my baby to be okay:( If there's something I need to buy or do please let me know, I've honestly dropped hundreds on this fish and Id do it again. If I can avoid a vet that would be great, looking into the few nearby they seem to have not the greatest reviews.
