so i noticed one of my fish was turning lighter in color, skinnier, and looking kind of ill, i put her into another tank which was empty and after a while a worm is coming out of her bumhole. half of the worm looking thing if clear and the other half is whitish... it looks to be a dead worm? well beside that worm looks like something else is coming out of the bumhole but its only peeking out so maybe it could be poop or another worm... any way i can help the fishy or nothin i can do? pull the worm out maybe? she doesnt seem like shes into much anymore, cant eat but she still darts for the food.. very skinny also, she never was this skinny befor, she eats like monster usualy
