Well Kenshin has some problems swimming.
He stays (more like floating) on the top if his tank, most of the time on his side. He can swim down but he comes right back up, floating sideways.
I noticed that he was acting funny about two days or so ago. It got worse since last night. He is usually active. He was staying right by a fake plant that I have. I think he was using it to keep himself down.
He is in a 1 gal tank, no heater at the moment (room stays pretty much a consistent temperature). Water stays around 78-80 Degrees. Not cycled. Gets 100% Water Change once a week with a 25% water change during the middle of the week.
I just changed his water completely today and added aquarium salt. I haven't feed him since the problems showed up. I last fed him Friday night, about 4 pellets of wardley betta food. I usually feed him this amount of food, once a day. Fasting them once a week.
Any ideas what is going on and what else should I do?
