I have a Betta with bloated stomach and likely constipation. I heard it is good to fast him for a few days. Since he is in a community tank, should I fast him together with the rest or just him. Would he be too hungry and hunt for my other tiny fishes? They been peaceful for many months till now.
You could also buy a floating mesh breeder box and stick him in there in that same tank for a few days so you could monitor what he’s eating and see if he’s pooping. Community bettas will often overeat because they are great at cleaning up all the food that the community fish don’t notice right away.
