    But even if you aren’t the biggest Sponge Bob fan, you can’t deny the intricate beauty this décor provides you and the extra swim and hiding space it offers your fish. Your fish will spend hours swimming in, out, and through this solid piece of décor. A quick wipe down a couple time a year should keep it free of moss and debris buildup.

    7. GloFish Aquarium Plant

    GloFish

    Turn your aquarium into a psychedelic playground for your fish to enjoy using the GloFish Aquarium Plant. This bright plant doesn’t look lifelike, but it is a lot of fun. It goes with the flow and sways in the water to provide your fish with a little variation throughout the day.

    This product includes a rock substrate that makes it easy to simply bury the base of this plant into your aquarium’s gravel. The GloFish Aquarium Plant comes in a wide variety of colors, making it easy to customize the look of your aquarium from one end to another. But this budget-friendly option may not hold up if the other décor options on our reviews list.

    Cons
    • Un-lifelike design that won’t fool anyone

    8. Sporn Static Cling Coral Aquarium Background

    Sporn Static

    An excellent way to spice up the look and feel of your aquarium is to install a Sporn Static Cling Coral Aquarium Background. This background will cover the entire back wall of your aquarium and give the space more depth without taking up any actual real estate inside your aquarium.

    You can round out any aquarium design and make the interior look dense without having to invest in several different types of coral and plant decorations. The only downside is that this background won’t provide your fish with any engaging activities to take part in, although it should help stimulate their sense while exploring the other aquarium features that are in place.

    • Engaging background that will fill out any aquarium
    • Easy to install and keep clean
    Cons
    • Doesn’t offer much engagement for fish
    • Can start to lose its static cling after some time of use

    9. Nature’s Ocean Natural Coral Aquarium Base Rock

    Nature's Ocean

    We added this pick to our reviews list because it comes in bulk, so you can cover your entire aquarium bottom with it. This base rock even acts as a natural, non-porous filter that will help keep your tank’s water clean as time goes on. But, as far as décor goes, this is an option that is pretty boring on its own. Without the addition of other types of aquarium décor, you can expect to look at a bland aquarium that both you and your fish will likely find uninteresting.

    Pros
    • Comes in bulk so you the entire aquarium can get covered
    • Offers natural filter performance
    Cons
    • Design isn’t very exciting
    • Requires the incorporation of other décor for a full, lush looking design

    10. Otterly Pets Aquarium Plants

    Otterly Pets

    This is a budget-friendly décor set that will allow you to fill out your aquarium without having to purchase multiple different products. There isn’t a lot of color and design variety here, but for the price it’s hard to complain about the basic design. And the lightweight plastic build may mean that you will have to replace the set before too long.

    Pros
    • Budget-friendly decorating option
    • Includes eight faux plants
    Cons
    • Flimsy design that may not hold up long
    • Can be tough to keep buried in the base rock

    Buyer’s Guide

    When it comes to buying aquarium décor, you should always keep your fish in mind. The activities that you observe them partaking in and the type of foliage you know that they like should be a part of your décor whenever possible. When you are introducing a new piece of décor into your aquarium setup, take note of how your fish interacts with it. If your fish tends to ignore it, you may want to focus on other types of aquarium décor in the future.

    Features to Look For

    There are a few key features that should be considered when purchasing new décor for your aquarium. First and foremost, a solid build should be at the top of your list. What’s the point in buying décor if it’s just going to break down in the water after a couple of months?

    You should also look for décor that features heavy bottoms or special stakes that will make it easy for you to install the décor. Pieces that are easy to keep clean should also be a priority, otherwise, you may find yourself having to fight moss and mold buildup throughout the year to keep it in good shape.divider-fishbowl

    Other Considerations

    When choosing new décor for your aquarium, it’s a good idea to read the fine print of the manufacturer’s warranty (if one is included) so you know exactly how to get your décor replaced or repaired if necessary. You may also want to consider the materials that your current décor is made of, so you have an opportunity to choose complementing materials.

    Knowing what the materials are made of will help you determine whether the décor will be safe for your fish and your aquarium. If you are ever in doubt, there are plenty of other décor options to choose from so don’t be afraid to skip over something cute, interactive, or lifelike in fear that you won’t find a safer option – because chances are that you will.

    We hope this list of the best aquarium decoration reviews is helpful and makes the job of buying décor for your own home’s fish tank a cinch.  Our number one choice of aquarium décor is definitely the Marina Polyresin Cave Aquarium Décor because of its interesting design, easy to install functionality and sturdy build. Out vote for number two overall is the Penn-Plax Squidwards Home Aquarium Ornament due to its deep cozy swimming spots for fish and its ability to blend in with a host of different kinds of aquarium décor.

    But the truth is that you can’t go wrong with any of the aquarium décor options that you find on our reviews list here. Do you have any suggestions of your own?  We’d love to hear about it in the comments section below!
