Hi there, I came home to find something hanging out of the side of my female guppy (see picture attached) and she had white stringy poop before I took the picture. She's active and swimming like she always does. I did a little research but couldn't really find an exact match. Any idea what this might be and what I can do? Much appreciated. About the aquarium: - 8 gallons - 2 guppies (1 male and 1 female) and 2 ghost shrimps - Not planted - Filter and air pump - Kept at 26 celsius (79 fahrenheit) The tank is new (3 weeks) and still cycling, but I monitor the ammonia/nitrite/nitrate levels using API test kit everyday after work. - Ammonia: 0.25 ppm - Nitrite: 0 ppm - Nitrate: 10 ppm I do a 25% water change daily. Feeding happens twice a day and excess food is promptly removed.
