Decoration Ideas for a 5-Gallon Fish Tank

Fish tanks can be beautiful works of art as well as a habitat for your pets. For small tanks, decorating can be challenging because of the lack of space; but by selecting a few choice items, you can make your tank just as attractive as a large one. Not only do tank decorations please the eye, they also please your fish by giving them hiding places and a more natural environment.

  1. Color-Themed Tank

    • A color-themed tank derives unity from one predominant color accented by one or two coordinating colors. This kind of theme is especially good for a 5-gallon tank because too many colors in a small space can be overwhelming. For example, if your background is mostly dark blue, cover the bottom of your tank with blue, white and brown gravel, then add some brown rock formations. If your background has red accents, continue that theme by adding some red-tipped plants.

    Object-Themed Tank

    • Themed tanks are not difficult to create, but require a judicious selection of objects so your small aquarium does not become cluttered. Choose a themed background, such as a sunken ship or a coral reef, then add a treasure chest or plants that resemble those found in a reef environment. You may also want to consider what kind of fish you want when planning a themed tank. For example, if you want a Siamese fighting fish, choose an Asian gazebo.

    Tanks for Bright Fish

    • When you want to purchase brightly colored fish, choose a substrate and background in a dark, mutted or coordinating color. For example, a school of neon tetras will look most brilliant in a predominantly black or dark blue setting. A red beta will often look even redder against a slightly more muted red gravel. Remember that in small tanks many contrasting colors can distract the eye. Showcase your fish by avoiding objects that compete for attention.

    Tanks for Dark Fish

    • Dark fish will look striking against a light background and substrate. For example, if you want to purchase black mollies, fill the tank with clear gems or white gravel. Add a plant or novelty item with a splash of color to prevent the tank from looking monochrome. Another way to make these fish stand out is to showcase them against rainbow gravel and green plants. Their dark colors will stand out in sharp contrast to their bright surroundings.
