I have a male betta who's going on 2 years old now. I've ton lots of moving tanks and inhabitants around, but now he resides in a 5.5 gallon heated, filtered tank. Perfect water params and everything. But over the past week he's been getting slower and slower, and resting more and more. Last night I accidentally left the light off, and when I turned the light back on to feed him he began to swim around but he looked like he was too heavy and was struggling to swim up at the surface. He also was not interested in the food, but I don't know if thats because I woke him up. The most distressing part is how he breathes. He will gulp air from the surface every 10-20 seconds when the light is on and he's trying to swim around, then he will jerk his head up in a motion reminiscent of coughing or choking. With any other fish I would think low oxygen in the water, but since he has a labarynth and the water has movement from the filter that shouldn't be the problem. If he's not swimming he will be resting on top of the heater, thermometer, or feeding ring but he doesn't do the gulping when he is resting. A couple times he did lay on his side on the bottom. He was able to swim back up though.
We ended up calling one of the better LFS in the area and asking them what they thought about all of the above, and they said he was probably dying of old age and that a water change and some salt could help a little. I did do the water change and added aquarium salt, he is just sitting on top of the heater now.
So, is just getting too old to live? I didn't expect it to hit him so fast though... I didn't post this in emergencies because I feel like more people with experience with older bettas would see this.
