Understanding their lifecycle is crucial for breeders and enthusiasts aiming to maintain the health and lineage of these captivating creatures.

Therefore it is crucial to maintain regular feeding schedules and only resort to fasting under unavoidable circumstances.


Betta Fish Survive ability to survive without food is a survival mechanism evolved from their natural habitat’s unpredictable food sources. In captivity however they rely on us for their nutritional needs. It is unethical to view their fasting tolerance as a convenience for our own irregular care patterns. Instead we should respect their biological needs and provide consistent nourishment which is key to their health and happiness.
