Some fish prefer swimming at the top of the tank while others the bottom or middle.
Could be anywhere.
reflection, refraction, and reflection occurs because of how the beam of light hits. and where it hits.
It means that you are to put the heads on the top of the fish tank. The heads come from the drawer in the attic and the rope in the living room. (:
Fish make bubbles at the top of the tank because they release excess air from their swim bladders, which helps them regulate their buoyancy and stay afloat in the water.
Angel fish are light sensitive. They figure that light is always coming from the sky, so, if the room light is brighter than the tank light and the tank has a dark top, then the angel fish will look straight up thinking that it is correct and wonder why you are lying down and floating.
