If he doesnt do it regularly and it doesn't impact the shrimp population, I would let him go along with this behaviour, I once purposely placed deformed guppy fry in my Betta tank, to further find out that my betta had exhibited a more vibrant color, and was a bit more active during the period that they were contained within the tank
Yeah, they actually swallow them if they get their mouth on them. I noticed that he had this white thing the first time i witnessed it. I was like omg is he choking on gravel? LOL then i was like holy crap hes chewing that shrimp tail down.
yes boys (and girls!) will happily chow down on shrimp. I caught one of my girls trying to swallow a half dead cherry shrimp whole (I mean half, my boy had just snapped him in half! so I tossed the rest into the sorority and the girls went vicious).
