What appears inside the aquarium

The tank is viewed from the front, with a rectangular glass body, a rounded lid, side supports, and a base. Aquatic plants grow on both sides. A larger fish swims through the middle-right area, while two smaller fish remain closer to the gravel and pebbles at the bottom; no aquarist or other person is present.

How a healthy aquarium works

Aquatic plants use light and nutrients to grow, and they can provide fish with shelter. Gravel gives beneficial microorganisms a surface on which to live, helping break down waste in a maintained tank. Fish species differ in their needs, so water temperature, space, and compatible tank mates all matter.

Natural colors for fish, plants, and the tank floor

  • Aquarium fish: silver, gold, orange, brown, black, or multicolored
  • Fish fins: translucent, pale, or brightly colored depending on the species
  • Aquatic plants: light green, deep green, reddish green, or brownish green
  • Gravel: tan, gray, brown, black, or mixed natural shades
  • Pebbles: cream, rust, charcoal, gray, or muted brown
Questions and answers

Questions and answers

Why do aquariums need filters?
A filter moves water and collects debris. It also supports helpful bacteria that process some of the waste produced by fish.
Do all aquarium fish live well together?
No. Different species may require different water conditions, diets, swimming space, or social groups, and some can be territorial.
Why do fish stay near plants?
Plants can offer shelter and a place to rest or explore. For some species, vegetation also resembles the protected areas found in their natural habitat.
