Hello, I recently addaded a dwarf Gourami to my tank, and shortly after he got an open sore near his mouth. any Ideas or suggestion would be greatly appreciated.
the tank is a 69 gallon hex with @ 40 gallons of water, heavily planted. The GH is @ 12 and the PH is 7.6. the temperature is 72-74 F. In the tank is 4 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%.
