it could affect the behavior because the betta will look for food at the time that you fed it. So try to keep feeding time within 30 minutes.
Short-term feeding behavior refers to an individual's immediate food choices and intake within a brief period, such as a single meal or snack. Factors influencing short-term feeding behavior include hunger level, food availability, sensory preferences, and social influences. It can impact overall nutrient intake and energy balance in the short run.
This behavior is known as parasitism. Leeches are considered parasitic organisms because they rely on other animals for their survival by feeding on their blood.
It is actually a long word but for short it is called Vampiretigia
The presence of carbon dioxide attracts bed bugs and stimulates their feeding behavior. Bed bugs are drawn to the carbon dioxide that humans exhale, which helps them locate their hosts for feeding.
Abnormal feeding behavior for a rabbit can result in health problems and developmental issues. Rabbits feed constantly throughout the day due to their poor digestive system. You should probably consult a vet.
