One of the factors often overlooked when choosing fish for a community aquarium is the level the fish prefer. Choosing fish that prefer swimming at different levels will result in a far more attractive aquarium, while at the same time assuring that your fish will not have to compete for space. It will also reduce the stress that occurs when fish have to battle for territories. Popular fish that swim at any level include:     Pearl Danio Rosy Barb Upside Down Catfish Zebra Danio  Top Level Fish Top dwelling fish add movement and color at the top level of the aquarium, which often has very little decoration. Many fish that prefer the top level are surface feeders in nature and have upturned mouths designed for top feeding. They hang at the surface waiting for the next meal to come along.  Middle-Level Fish The middle level is the focal point of the aquarium and should be populated with plenty of active fish. Schooling fish, including most of the Tetra species, as well as some of the Barbs, are excellent for the middle level of a community tank. Mid-dwelling fish are often selected as dither fish for cichlid tanks, particularly schools of active fish.  Bottom-Dwelling Fish Bottom-dwelling fish lend interest to the lower levels of the tank and often help turn over the substrate. You will note that most of them have mouths that point downward, making it easy for them to scour the tank bottom for morsels of food. However, do not fall into the commonly held myth that bottom dwellers do not have to be fed. All too often bottom- dwelling fish are under-fed. They cannot subsist only on leftovers from the other fish. 10.0 Easy Fish Tank Care and Maintenance Tips for Beginners If you keep at this aquarium thing it will get easier, and you’ll be a pro one day.
