I'm just wondering, how do you know when your Betta is getting old?
I'm not sure what's happening but I think maybe he just is. When I first got him, and even up until recently, He would be a very strong swimmer, love swimming in currents etc and really fast, but recently he has become less active, and not as much as a strong swimmer. He will swim really fast and try to stop and I see him bump into the corners of the tank a lot. I'm not sure if he's getting old or if he is sick... any advice would be great! Ta!

Symptoms and Treatment
How has your betta fish's appearance changed? Doesn't seem as "viabrant"
How has your betta fish's behavior changed?He's a tad clumsy now, he sleeps more, less active.
When did you start noticing the symptoms? Last week or two.
Have you started treating your fish? If so, how? I put Wunder Tonic in his tank last week and it's still running in the system.
Does your fish have any history of being ill? He had cotton tail when I first got him, but that is it. I put Wunder Tonic in his tank as it looks like his tail is "thinning" and suspected finrot.
How old is your fish (approximately)? I'm not sure. He was adult when I got him last year, but he has grown more.
Have you tested your water with a liquid test kit for ammonia, nitrites & nitrates? Just because the water looks clean does not mean it is good quality. If you are doing such few water changes it is possible the water parameters are out of whack & is causing an issue.
It could mess up his day/night cycle depending on how much natural light he's getting. I think like most creatures they like routine. I have all my tanks that have lights on timers so I don't have to worry about it.
Definitely can't only do a once monthly water change to maintain water quality. Sorry. I would do a series of 50% water changes over the next 3 days to get it back under control.
Also agree with the lighting. You can have it on during the day but it needs to go off at night so he can get good sleep. I leave my light on between 8-10hours daily and I make sure it's off by the time the sun goes down to keep him circadian rhythm up. Light goes on with the sunrise. Others will just use a timer but I observed when I keep my bettas in a room with the only light coming in through the window they will rise and fall with the sun and seem healthier, so that's just what I do.
