So I've had my betta for about a year and a half, maybe two years (I can't really remember exactly when I got him) and lately.. he just hasn't been doing so good. I don't really know what's wrong or what to do, so let me first say what's happened and then I will post all extra info.
So he was doing just fine, and it was feeding day. I used to always feed him 4-6 pellets every few days, no one ever told me to do it differently so I thought it was fine and it always had been. Well the next day he was floating around. He seemed to be well, like he didn't seem sick or lethargic he was just floating. I assumed this was swim bladder disease, went online to read up on what to do and saw I should fast him for 3 days then on the fourth day feed him a pea. Well on the fourth day he was no longer floating but seemed kind of tired, I'm assuming because he hadn't eaten. I tried to feed him a pea but he ignored it, tried to feed him pellets and he ignored those too. The next day he was still lethargic and I got him to eat two pellets. Well then the day after that he was floating again! I didn't know what to do, I couldn't feed him again because he seemed really tired and unable to get food. What made matters worse was the heat broke in our apartment, and the house dropped to 46 degrees, so even with the heater on in his tank, the heat in his tank dropped to around 72 when it's normally like 76-78. I went to stay with my parents Saturday and Sunday because of the heat not working and wrapped his tank in blankets to keep some sort of heat for him. When I came back last night, I decided to do a water change for him (I had just done one a week prior), and after he was now laying at the bottom. It seems like his coloring has faded -- normally he has a red patch on his head but it turned a sort of dull brown, his body is white with pinkish undertones but now it looks completely white. He has no energy it seems and could barely swim up. I sat by him for almost 2 hours watching him and finally he started to swim up to the top. He went by a tower I put in his tank and would swim a ways then stop and fall onto it, then swim a ways and stop. It seemed like he had no energy to even hover in the tank, he kept sinking. He went up to the top, and I got him to eat just one pellet, he wouldn't eat any more. This morning he seems to be floating again, though not as bad as when he originally had. Just the top of his head floats at the top of the tank and he seems to have issues swimming and turning. His body seems weak now.
Sorry that is a lot. I'm just really really concerned about him, I love him to bits and want to do whatever I can.
