I just seen one of my blue neon guppies poop a long white string(it was only about an inch long, sorta thick imo comparing it to pictures of actual worms). My girlfriend told me she seen the same thing yesterday or so. Doing some reading, it maybe worms inside him, or maybe just constipated. My fish are pretty active so its hard to see anything coming out his butt. I'd say none of them are bloated, but what is considered bloated for guppies? Are there anymore tells to check if there are worms? Bouns: How can you tell what ones female or male? Thanks.
