I saw a weird behavior on all my fishes. All the fishes was in the top part of the fish tank trying to breathe, I decide to put a new air pump (Whisper® Aquarium Air Pump for 40 Gallons) and the problem solved at the moment. Well at the moment I’m using a small air stone but probably later I’m going to replace it with a bubble bar.
