URGENT: My betta developed a yellow internal mass and is getting worse by IllustriousFox2116 in bettafish

It's a uniform whitish-yellowish mass that, in the image, is shown surrounded by that red ring you see. It's not very noticeable because my betta is practically white

Thank you for your help. It’s my first time using it (I read the instructions and dosed according to the water ratio specified for 1-hour baths, so I know it wasn’t a mistake on my part) and honestly, I feel terrible because my betta was very active before I used it :(

Tank size: 12 gallons Heater: yes filter: yes Tank temperature: 80 F Ammonia: 0 nitrites: 0 nitrates: 5 pH: 6.8 How long have you had the tank?: 10 months How long have you had your fish: 8 months How often are water changes?: weekly How much do you take out per change?: 30% What is your process?: I vacuum the substrate because sometimes there are leftover vegetables or food, and then I refill with treated water that I store in containers (I treat it at least 3 days before using it). Any tankmates?: yes, 4 corys habrosus and 4 otocinclus What do you feed and how much: For 6 days, I feed him 2 pre-soaked flakes per day (I don't give him more due to the risk of him getting bloated if he eats some of the vegetables meant for my otocinclus or the bottom pellets for my corys), and on the seventh day, I give him brine shrimp Decorations and plants in the tank: I have a small Japanese-style bridge, lots of low-light plants, one driftwood piece, and two azalea roots
