55 Gallon Fish Tank Ideas

A large aquarium can be a conversation piece, and setting up a 55-gallon tank can be a fascinating, rewarding hobby. Aquarium hobbyists have a number of choices in tank setups, but a 55-gallon aquarium generally is easier to maintain than a smaller one. Small tanks are more subject to water quality fluctuations, while larger tanks tend to be more stable.

  1. Coral Reef Tank

    • Many people find saltwater fish much more interesting and colorful than freshwater varieties, but it can be difficult to maintain a small saltwater tank due to changes in water quality, temperature and hardness. A large saltwater aquarium is easier to maintain and a 55-gallon tank is an excellent size for recreating a coral reef in your room. Stock the tank with a variety of live rock, corals and reef fish and bring nature's beauty indoors.

    Cichlid Tank

    • Cichlids are among the most engaging of all aquarium fish. Some species actually get to know their owners, and they frequently swim up to the glass to look for food. One potential problem is that these fish can get quite large. Oscars, for instance, can grow to 10 inches or more, and the popular Discus is nearly as large. Setting up a 55-gallon tank as a cichlid environment will give all residents plenty of room. Having ample space also reduces the territorial nature some cichlids display. When setting up a cichlid tank, use plenty of rocks to form caves throughout the aquarium. Cichlids need secure places to hide and retreat, particularly when brooding and rearing their young.

    Community Tank

    • A community tank can be attractive in any size. A 55-gallon aquarium gives community-friendly fish ample room to swim and set up territories throughout the tank. Stock a 55-gallon aquarium with schooling fish of assorted sizes and swimming patterns to add life and vibrancy to your tank. For an interesting mix, choose some fish that swim near the top of the water, others that prefer the middle areas and some bottom dwellers like catfish and loaches. This is an effective use of space and keeps the tank visually appealing. For a natural look, add many plants, real or artificial, and various rock and driftwood formations.
