How does the flow rate in the X-Ray Tetra's preferred habitat relate to the oxygen saturation levels found there?
Answer
Lower oxygen saturation compared to rapids
The X-Ray Tetra prefers slow-moving tributaries and weedy areas, which inherently feature less water turbulence compared to the main river channels or rapids. Water that lacks significant movement or agitation absorbs less atmospheric oxygen, resulting in a lower dissolved oxygen saturation. While good aeration is always required in an aquarium setting to compensate, the natural condition in these calm, backwater habitats is characterized by this reduced oxygen level relative to more agitated waters.
