My fish wont eat help
Give it a green pea, sometimes they get constipated (basically.) Google about the green pea method... some people say frozen, or skinned.But you need to make sure that you control how much you feed it from now on, because overfeeding is what can cause the "constipation."
try diff food
sometimes mine dosent eat as well, how long has it been going on for? sometimes, they just have there moments, mine does every now and then.
try bringing the food right down to his mouth - that is what i do when my glass catfish won't eat so it should work for your betta fish
Try different food brands!!
