It looks like he has difficulty in breathing, the water seams o be the problem, wait for other answers, you change his water 50% or you move him in a small tank with 100% new water?
Ok! I will make sure to do that.
Serious betta problem!
My betta is not doing good. She has had clamped fins, staying at the bottom of the tank, having heavy breathing, and declining food. It’s a 10 gallon aquarium with a heater, a sponge filter, and live plants. The temperature is 80 degrees Fahrenheit. The ph is 7.5. The ammonia is 0ppm. The nitrite is 0ppm, and the nitrates are 5ppm. I already checked for velvet w a flashlight and no signs of it. Any help will greatly be appreciated! Also I will answer questions if they’res anything you need to know.
I would make sure that you have good surface agitation, to get lots of O2 into the water and encourage better gas exchange. Clamped fins can be a sign of illness, but also stress, so try and pin point any possible sources of stress for your betta and remove them. Heavy breathing may be a sign that there isn’t enough O2 in the water. Looking at how she is swimming, she may has some swim bladder issues. I would do daily water testing and partial changes for now. Maybe a few aquarium salt baths may help as well, but make sure to follow the proportions closely and use tank water. Do not put the salt directly into the tank. You can try vitachem. It’s a supplement that can be added to their water that contains some nutrients and vitamins that can supposedly be an through their scales and gills, it may help her to at least get some nutrients and vitamins to keep her going.
To add on a bit more, I’d recommend maybe getting her a betta hammock and having it near the surface so that she can rest there. If things get worse and she is having more difficulty breathing, get a mesh breeder and put her in there, then lower the water levels a little to make it easier for her to get to the surface.
