Betta Fish: I had to euthanize my betta and I’m distraught

I got Fin (short for Fin-tervention) at a pretty rough point in my life. I was going through a lot of mental struggles and I was living alone in a place where I had no support. I went to the pet store and picked out the most pathetic looking, longest resident – Fin was there for 6 whole months living in his tiny cup before I took him home. His tank sat next to my bed and every single morning, as soon as I lifted my head, he’d frantically swim over and start dancing around. He reminded me of a dog, it was so funny and so cute. He would see me walk in the room (his tank was seriously all the way across the room, so it’s crazy he could even notice) and fly across the tank to greet me. He genuinely became my best friend and I looked forward to seeing him when I came home every day. I would sit by his tank and talk to him. I swear he knew his name. I’m a college student and he came back and forth with me over breaks. He’s been on 4 flights. In the year I had him, he had a massive glow up and ended up absolutely gorgeous. But, he was a dragonscale and ended up growing a tumor. It didn’t affect him for a solid few months, until just a month ago he started having swim bladder issues and refusing food. The tumor was growing on his side where his swim bladder and stomach were. I moved him to a hospital tank and hand-fed him bloodworms for 3 weeks. He continued to eat the worms pretty eagerly but two days ago he suddenly lost even more energy and didn’t seem as enthused by the bloodworms anymore. Yesterday, he stayed in one spot for a full 24 hours without moving. Today I made the decision to euthanize. I’ve cried after all of my bettas, but this time was different. I’ve been on and off sobbing throughout the day. I graduate in 2 weeks and was thinking about how he would graduate with me. I’m genuinely so distraught about this fish, I really loved him. I buried him by a tree where my past betta was buried, and put some of his Java moss in there with him. I sprinkled wildflower seeds over top too. I won’t get to see them sprout because I’m moving in a month, but I hope they’re as pretty as he was
