Clown with stringy poop

[Jrco226]

A few days I noticed my male clown had some really thick stringy poop. Not thin and white like I see a lot with a parasite. What are you're thoughts and fixes?

i think I've heard somewhere that fish that do that need better quality food because it should be stringy.
