Ideas for Decorating a New Aquarium

I have been keeping fish for over ten years, and I've always found that my favorite part of getting a new tank is determining how to decorate the tank. Aquascapers have developed hundreds of different themes, designs and layout ideas for decorating a new freshwater aquarium. To make your new tank look its best, follow a single motif or theme; this will keep the tank cohesive and visually appealing. Depending on the size of your new aquarium, the fish you are keeping and your own personal tastes, you might consider some of the following ideas for decorating a new aquarium.

Biotope Theme

Many serious aquarists prefer to set up freshwater aquariums in a biotope style. Biotope tanks are designed to closely mimic a fish's natural environment and they vary widely in their presentation. For example, a fishkeeper who likes tetras may keep tetras and discus in a blackwater tank with driftwood and peat filtration. African cichlid lovers may keep several species in a rocky lake that mimics Lake Victoria. The possibilities are limitless and the finished piece has a uniquely natural aura.

Island Motif

Aquarists who prefer the natural look of a biotope aquarium may not enjoy tropical, beach or island-themed aquariums. However, when properly executed, an island motif for decorating a freshwater aquarium can be surprisingly tasteful and aesthetically pleasing. Sand substrate, smooth sand-colored stones, natural seashells and realistic artificial palms can look elegant with brightly-colored fish. I enjoy placing decorations on a slightly raised platform in the center of an aquarium, with the rest of the area lined with sloped sand. This makes the aquarium look distinctly island-like.

Ocean Style

This idea for decorating an aquarium is related to the island theme, but it is more realistic and some find it more tasteful. An ocean look isn't limited to saltwater aquariums; aquarists can use the ocean look for freshwater fish as well. Use sand or aragonite substrate with crushed seashells and artificial coral. Plants should be used sparingly, if at all, in an aquarium with this theme; L.E.D. lights can offer an additional marine-like ambiance. Brackish water fish like mollies and pufferfish benefit from the chemistry of an ocean-style aquarium even if little or no salt is added.

Sunken Ship

Executed alongside the ocean theme, sunken ships and other pirate-style ornaments can look stunning. Use the classic ornaments for the ocean theme along with realistic sunken ship ornaments. I find that those with fabric sails look elegant and mysterious. For this slightly eerie theme, subdued lighting is a must and brightly-colored fish like neon tetras can create a treasure-box effect. Some aquarists may take the theme a step further and add aircraft, bridge or building ornaments to create an Atlantis-like appearance. Small pieces of driftwood can give the water a "tea-stained" look.

When selecting an idea for decorating a freshwater aquarium, be sure to stick with a single motif. Don't mix waving divers or Spongebob ornaments with natural driftwood; these decorations clash and look unprofessional. Always keep the needs of your fish in mind; some fish need the gentle acidity of driftwood, while others benefit from the alkalizing effects of aragonite or crushed coral. The employees at your local fish store can also be a valuable resource for helping establish your new tank.
