My mandarin (Dilly) has terrible eyesight. While feeding her some Ova she latched onto a bristle worm! I did not see her spit it out. I turned my head for a min and no more bristle worm. For a couple of minutes she was gulping and shaking her head big time. She's since settled down and is acting normal but I'm concerned that she may have swallowed the worm. If she did, will this kill her?
