One of my 3 discus has been staying in one corner, has dark colors, won't eat and has been leaning on occasion. The other two are fine. Any suggestions?
Ammonia- 0
Nitrite- 0
Nitrate-18
pH- 6.5
Temp- 80
This has been going on for several days. I had one fish die about a day before and then had a nitrate spike to around 30 ppm. I've been doing daily water changes to get levels back down.
ALSO: I noticed what looked like slime coming off him when he has looked at his worst.
