I am pretty new to this hobby and just got a water box peninsula 25 gallon tank. My pump as you can see in the video, has produced a lot of bubbles at the top making for splashing and getting the back mirror and the sides of the tank fairly wet. Is this too high of a setting or is this normal? I can maneuver the flow downward which seems to fix the splashing but I have heard that there is supposed to be some water movement on top so I don’t know if that is the right move. Also the second video shows my clown at the bottom of the tank, it looks like he is breathing heavy almost gasping for air. Does my tank have to little air going through it or it normal for clowns to do that? Thank you for the help
