Hi,
I just started my dirt planted tank with roughly 1 inch of substrate. Every went well but after I planted my Eleocharis acicularis, there was a cloud that emerged from the soil.
I suspected the substrate was leaky so I put substrate layer on top of the previous, but the yellow cloud still...
I live in a tropical country and Betta is by far the hardiest fish I have ever got. They can live through almost every stage of my aquariums, while still shine bright !
I believe the symptom means the fish is stressed.
My SAE also changed color to white/silver when I move him to a new tank. He was very aggressive at the original tank so I had to move him, only to see him get worse. Now I don't know what to do to help; I can't move him back as the catching part...
