Hi mi 2.5 inch betta fish isnt eating, period. This started yesterday. I fed him perfectloy fine on new years day but i tried yesterday and got now result. I tried to clean it and did so, but nothing happened, teh exact same behavior happened. Now I considered the possibility of old age, but the change was so absolutely spontaneous. Also, he is moving very well when he is nudged to do so.
What will happen is he will chill at the bottom of the bowl, and will mvoe upwards when prodded. He then bites for food and then circles teh bowl. Even if he sees the food while cirling he doesn nothing, he then falls to the bottome fo the bowl, staying limp in either horizontal positions or in a semi bent position
im not sure if it is a girl or a boy
remember this was extrmely sudden and random
