Darkmoon, I got a male beta about 4 months ago. I thought when a fish pooped, it was stringy, but his is round, he, for some reason, does his biggest poop every 6 days, when I cup him. He doesn't appear to be stressed when I'm cleaning his tank. The only time I notice he has a large bm (at least twice his usual size) is when he is cupped. Should I be concerned?
