Hi there, I've got a veil tail male betta living in a well-maintained 1 gallon tank.
He is responsive, active, and apart from a healing ripped caudal fin, quite healthy.
He eats well. However, I've always noticed that when I feed him pellets, he will eat the majority of the pellet and always spit out a tiny bit out at the end. So I've developed a habit of always watching him about 5 min. after I've fed him to make sure that I can quickly scoop out the food he spits out.
But I've noticed recently that as he chews his food, lots of really small food particles come out from underneath his gills! The particles come out in such a way that his pectoral fins flap them away from his body immediately.
I am sure that it is his pellets that are coming out of his gills because when I feed him red pellets, red particles come out and when I feed him green pellets, green particles come out.
Is this even possible? Have you ever seen your betta do it? Is it healthy/normal?
Thanks for all your help.
