I had another round of endler fry born yesterday. As I was watching them last night, one has a strange yellow fringe on its belly. It is very hard to really see (I mean, they're only about 1cm total length). I isolated it and tried to take photos, as much to get a clearer look as to share. I pretty much failed, but here is what I have. The yellow spot below the normal belly is what I'm referring to, and when viewed by the naked eye it seems a little jagged. Could this be the remains of an external egg sac? I thought about keeping the little one separated for observation, but it was very stressed so I added it back to the main aquarium. It's swimming fine (AND FAST), and the "fringe" was still there this morning. I'm willing to just wait and see with this, but I was just wondering if someone had seen this before. At first I was worried it was a perforation in the abdominal wall, but I couldn't see it clearly enough to determine that. Where's my microscope when I need it! (Oh yah, at work).
