Hello i have a fish tank 45l with 11 fishes in it (Shubunkin , opaline gourami , honey gourami , trichogaster etc) . i added the fish a week ago and tested the water and it was fine.today i see that 2 of my Scalars aren't eating like everyone else , so i tested the water . Everything was fine except for Nitrite levels that was 3.0 - 5.0 ppm. I changed 25 % of the water and added Easy Life Filter Medium and after some hours i tested again the water quality and it was the same I also added salt

I have 2 salmenese tiger fish and two smaller fish in approximately 3.5 L bowl. I bought them on 1 April. 3 act normal but one act abnormal from first day. One salmenese tiger fish doesn't move much first it stayed at bottom now it's gapping at surface and if I try to catch to check it it goes down again. It's fins are turning red or I don't know if it already was. I don't understand how to help. Parents are out town so I can't go to shop. I am not sure if all are eating food.
