David Ellsworth Posted October 22, 2020 Share Posted October 22, 2020 I went to feed my guppies this morning and saw all of my fish looked fine except for one little guppy fry. He has a strange white blob/bubble near his backside. Is it something to be concerned about? This is a heavily planted 30 long aquarium that has been set up since July 2020. PH: 7.62 Temp: 72.4 F GH: 180ppm (10 drops) KH: 50ppm (3 drops) Ammonia: 0 Nitrite: 0 Nitrate: 5 Link to comment Share on other sites More sharing options...
KBOzzie59 Posted October 22, 2020 Share Posted October 22, 2020 Yep I've have one pop up now and then. Just a defect. Link to comment Share on other sites More sharing options...
Alesha Posted October 22, 2020 Share Posted October 22, 2020 I have one of those too. I always suspected that it was that their yolk sac didn't absorb when it should have. I did euthanize a little one with this, as it wasn't doing well. But the one I have now is growing just fine, so I'll leave him be. Link to comment Share on other sites More sharing options...
David Ellsworth Posted October 23, 2020 Author Share Posted October 23, 2020 Oh, the poor little guy. I'll just monitor then. I didn't see anything like this before and didn't look like any of the common diseases. Thanks for the reply all. 1 Link to comment Share on other sites More sharing options...
