Hello everyone,
First I will describe my tank setup its a 90 cm x 40 cm x 40 cm tall aquarium It has been running for more than a month I seeded it at the start with a filter from my established tank. and a 1" Angle fish and a black skirt tetra has been living in it since. It has two hang-on filter with total 750L/H. Black/Dark brown gravel substrate with some blue yellow stones scattered. No background yet and 2 plastic plants and 2 live plants.
water conditions before adding the discus and making a 70% water change:
pH= 6
NO2=0
NO3= 10ppm
GH= 13
KH= 6
I bought the pair of Mature Discus today they were kept in a small tank with no filter!! but showed nice pattern and activity, slightly dark tint at the center of the males body. When I arrived home after an hour of driving I found that the male turned really dark. the female only slightly dark.
Now I read that this could be due to two reasons a parasite or a virus (black plague) or it could be due to stress
How can I tell which is it and how can I let them restore their color back?
