Frequently Asked Questions about Aquarium & Fish Tank Decorations

Do fish tanks need decorations?

Fish tanks do need decorations, as they provide a habitat for fish and places for them to relax. Tanks without adequate decorations may stress your fish and cause them to seek refuge behind heaters and filters. Creating a nice habitat with fish tank decorations will help your fish feel more secure, and it can enhance their health and natural coloration, too!

What are fish tank decorations made of?

Fish tank decorations are made of a variety of materials. You can find manufactured fish tank decorations made of aquarium-safe plastic, ceramic, resin, silicone or rubber as well as plants made from fish-safe plastic or silk. Natural aquarium-safe fish tank decorations include wood, rocks and live aquatic plants, but be sure to only buy items that are specifically labeled as safe for the type of aquarium you have.

What decorations are safe for fish tanks?

The decorations that are safe for fish tanks include ornaments and artificial plants that are made specifically for use in aquariums. Using household items or even natural decorations like rocks or driftwood may upset the chemistry in your tank, poison your fish or introduce harmful microbes into their environment. The safest bet is to only use decorations labeled for aquarium use.

How do I keep my fish tank decorations from floating?

Keep your fish tank decorations from floating by burying their bases under the substrate or by using aquarium weights or anti-float rings for aquarium plants. Decorative aquarium-safe rocks can sometimes be strategically positioned to weigh down lighter fish tank decorations. You can also use suction cups or aquarium-safe epoxy to secure some decorations in your tank. Many manufactured fish tank decorations will be heavy enough to keep from floating on their own, while others are intentionally designed to float and create a more interesting environment for your fish.

How do you clean fish tank decorations?

Clean fish tank decorations using warm water and a bristle cleaning brush to remove algae. You can also make a 5% bleach solution using 4 teaspoons of bleach in 2 gallons of water to disinfect your tank decorations. Be sure to rinse all fish tank ornaments thoroughly if you use a bleach solution, and you may want to soak them in a dechlorinating solution afterward to avoid upsetting the chemistry of your tank. Most aquarium experts recommend avoiding soap for cleaning fish tank decorations, as failing to remove soap residue could be harmful to your fish.
