I have a 4 in front that has always seemed to have an issue with keeping food in his mouth once grabbed from the surface. I have been feeding him small hikari pellets and most of the time he will take the food into his mouth then spit it out immediately after, only to go darting back after the same food he just spit out, having the same constant battle resume. The pellets are pretty small and he takes them in like nothing so I dont know why he is having trouble devouring. Its like only after trying ten times will he finally ingest one pellet. any help??
