I noticed as my biggest Endli was swimming around he has some sort of a pink/red color centered on his underside from his pectoral fins going to about his butt.... I don't think I have seen it before I am wondering what it might be I am rather concerned
He is eating well and acting normal but if he has some internal bleeding or something I want to know 
This may sound silly but I love my Endli's please help
