Instructions
Keep your goldfish tank decorations simple for ease of maintenance. Goldfish need plenty of room to swim around safely so do not fill the tank with too much decoration.
Limit yourself to small flat rocks in your goldfish tank. Goldfish will sift through gravel all day and you do not want them eating small pieces of gravel or cutting their mouths on sharp stones. Large rocks should be avoided in the tank as the goldfish could get stuck between the rock and the side of the tank or injure himself when swimming by scraping himself on a rock.
Put live plants into your goldfish tank only if you are prepared to replace them on a regular basis. Goldfish love to much on aquarium plants and will often eat a new plant up in a few days. Plastic plants are a good idea for a more permanent tank decoration.
Avoid any tank decorations with holes that are too small for the goldfish to swim through without touching the decoration. Scraping themselves on decorations while trying to swim through holes that are too small can cause skin irritation and injury.
Use a tank heater if the room temperature where the goldfish tank will be housed is lower than 74 degrees. Goldfish are healthiest and happiest at temperatures of 74 degrees Fahrenheit and above.
How to Decorate a Goldfish Tank
When setting up your goldfish tank you might want to decorate it to make it more attractive or make it complement your home decor. However, decorating a goldfish tank is not really necessary because the beautiful colored goldfish decorate it wonderfully themselves.
