Now, I’ve been keeping betta for years.. no betta bowls, just planted tanks above 5 gallons. My female betta that I’ve had for around 2 years (bought her at a year old, so she’s 3) has been lethargic, I still get her to eat but it’s on her own time, not when I first drop it in. She was in my community 29 gallon with peaceful fish and when I started to notice she got slower. I removed her and put her in a smaller tank where I can monitor her and feed her food individually just incase she wasn’t getting enough food. 3 days have passed and she’s still the same. Sits at the bottom most the time, I now have to feed her sinking food since she never comes up. There is no physical signs of stress, or sickness. No color loss or anything. Anyone have ideas ?
