Types Of Fish
The fish swimming at the top of the tank after a water change could be categorized into two types based on their swimming behavior: top swimmers and bottom dwellers.
Top swimmers are those fish that prefer to stay near the surface of the water. They have a natural inclination to explore the upper regions of the tank, often darting around and exhibiting vibrant colors. Examples of top swimmers include guppies, bettas, and danios. They are known for their lively and active nature, bringing a dynamic element to the aquarium.
On the other hand, bottom dwellers are fish that tend to spend most of their time near the substrate or the bottom of the tank. They are more sluggish in their movements and are typically well-adapted to scavenging for food particles that settle there. Common bottom dwellers include catfish, loaches, and plecos. These fish can be intriguing to observe as they probe the nooks and crannies of the tank in search of sustenance.
