I have a 58 gal planted tank. Inhabitants: 4 fancy guppies, 3 clown loaches (3ish inches...I know they will outgrow my tank), 8 orange von rio tetras and until a few minutes ago 1 dwarf gourami.
Test results (from right after I found dead fish)
ammonia: 0
nitrate 40
nitrite 0
I do about 20% water changes every Saturday, but last Saturday I did 50% and rearranged the tank (plants and rocks).
The last fish I added was the gourami, about 3 weeks ago.
I did notice about a week ago a long thread like worm in the gravel.
The gourami looked good (no redness, no damage anywhere) except he was on the bottom on the tank dead.
What should I do now? I am going out of town tomorrow and won't be back until really late Monday. I have a trusted fishy person coming in to feed all of our fish and our dogs while gone.
Thanks.
