Dear uncle Ned
I was looking at 75 gallon aquarium and I saw that all of my fish were close to the bottom and there mouths we're moving rapidly so I went and checked my water and every thing was fine
In the tank I have
12 African cichlids
1 albino Oscar
1 Pleco
1 synodontis
1 raphael cat
And another small cat
I was wondering if anything like this happened to you if so can you tell me how to treat it thanks
P.s. the Oscar is new
