Stocking Your Aquarium Evenly |
Stocking Your Aquarium Evenly |
One of the factors often overlooked when choosing fish for a
community aquarium is the level the fish prefer. Choosing fish that prefer
different levels will result in a more attractive aquarium, while assuring that
the fish will not have to compete for space.
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.
Keep in mind that some of these top-level species are strong jumpers. Hatchet
fish are known for being able to leap several feet out of the water. Take care
to keep the tank well covered, and close the lid promptly after feeding or
performing maintenance.
Middle Level Fish
The middle level is the focal point of the aquarium, and should be populated
with active fish.

Schooling fish are excellent for the middle level
of a community tank. Larger fish such as Gouramis, Rainbows, or
Angels also make interesting mid-level fish.
Keep in mind that slower moving fish with long flowing fins may be picked upon by smaller faster moving fish. Barbs are particularly well known for nipping fins. Avoid combining them with Angels or Bettas. Bottom Dwelling Fish Bottom dwelling fish lend interest to the lower levels of the tank, and often help clean the substrate. You will note that most of them have mouths pointing downward, making it easy for them to scour the tank bottom for morsels of food. When combing bottom-dwellers with other fish, keep in mind that top and mid-dwelling fish will get to the food faster. Including sinking foods when feeding will ensure that those living in the lower portion of the tank receive enough food. Some bottom-dwellers are nocturnal, and should be fed after turning the lights off for the night. Choosing Fish Always research the fish you are interested in for your community aquarium. For a quick reference, here is a level chart that lists 100 community fish separated by the level they prefer. Don't forget that your fish must also be compatible in preferred water conditions, size, and temperament. |
