Hello, I have a guppy fry that is about 4-6 weeks old. (It somehow managed to hide long enough to not be removed or eaten. ) It now has a trail hanging from it's behind. it has been there for at leas a week.
Any ideas what this is and if I should be concerned.
The tank is a 69 gallon hex with @ 40 gallons of water, heavily planted. The GH is @ 11 and the PH is 7.6. my amonia is 0 ppm and my nitrate & nitrites are fine. the temperature is 73-75 F. In the tank is 3 Otto cats (Otocinclus vestitus) 5 Colombian red blueTetra (Hyphessobrycon columbianus) 3 Pangio oblonga (Black Kuhli Loaches) 1 Dwarf Gourami (Colisa lalia) 5 male guppies @ 12 Ghost shrimp (Palaemonetes Sp.) 3 Eastern Red-Spotted Newts (Notophthalmus viridescens viridescens) 1 Gray tree frog (Hyla Versicolor). I do frequent small water changes of about 10%.-20%
I THANK YOU in advance for your time.
