The Absolute Best Aquarium Decorations for Every Holiday

Aquariums are for all ages. Whether it’s for a kid’s bedroom or a fancy living room fixture, a nice-looking fish tank is a wonderful way to enhance a living space.

Sure fish don’t do much, but they’re still so much fun because you get to shape and design their living space.

Around holidays, they’re an especially fun thing to decorate! Small ornaments and trinkets are a good place to start. We made a list of the cutest and most clever decorations, plus which pet store to find them at, so you can add a little spirit to your aquarium or fish tank, whatever the holiday!

Kissing Goldfish

Love is in the air when Valentine’s day is near. Get in the mood for love with these hand painted cuties.

This Kissing Goldfish ornament is safe for freshwater and marine fish tanks.

With this decoration, a swim hole is created for fish to swim through. It’s a little bigger than your average trinket sized ornament, so plan accordingly when fitting it in your tank.

Bedazzled Heart Framer

Another romantic choice for Valentine’s Day are these bedazzled heart framers from Walmart for the traditionally shaped fish tank.

The colorful detailed hearts provide a Valentine’s Day theme to any room. The framers stick easily, so no other tools are required.

Valentine’s Day Rocks

Ok, ok, one more Valentine’s Day decoration item!

These gorgeous white, pink, and red rocks are a lovely choice for decking out your home in Valentine’s Day colors. They’ll be perfect next to the vase of vibrant red roses!

These non-toxic translucent acrylic crystals are inexpensive and won’t fade in the water, staying bright every year for V-day.

This isn’t going to be the only PetSmart item on the list, so make sure to check RetailMeNot and other coupon sites for PetSmart promo codes before you buy!

Four Leaf Clover Plant

This next aquarium decoration is a little different. It’s technically not a decoration at all, but a plant.

When you’re St. Patrick’s day party rolls around, your friends will not believe that your fish tank is full of four leaf clovers. They’re known as “Water Shamrocks.”

These clovers (technical name: marsilea quadrifolia) grow underwater. They are absolutely perfect for St. Patrick’s day and cool enough to just keep all through the year.

They’re undemanding and can be grown in little light. Moreover, they can work as natural filtration, though you should have a good filter installed in your aquarium none the less.  Get the luck of the Irish and plant these guys in your aquarium!

Guitar Octopus

This next aquarium decoration is perfect for Cinco de Mayo! This little octopus with his adorable sombrero is a great addition to Cinco de Mayo decorations you already have up.

Look how cute he is!

He’s only 1.75 inches tall, so he should fit in most fish tanks.

American Flag Decoration

The fourth of July means American flags everywhere. Even underwater!

The American Flag skull is a fun way to show your patriotic side in a subtle way.

You could technically bring this skull back out for Halloween, so really, it’s a two in one!

This neat ornament is made with polyresin and is well created with attention to detail. It’s only a little over $20, yet it looks very nicely made.

This also makes a clever idea for people who consider themselves the patriotic type year round.

Zombie Fish

Halloween decorations aren’t just for you. Your fish wants to decorate, too!

Add a spooky element to your aquarium by adding a zombie fish to your fish tank. Hopefully the fish don’t get too scared! This one, from Petco, is a real bone-chiller.

Turn off off the lights and it offers a glow-in-the-dark feature.

Sure this piece of decoration is scary, but it actually offers a little shelter hideout for fish.

Skull Crawler Decoration

Skulls are always a neat decoration but around Halloween, they’re a must!

These creep-tastic skulls from Amazon will be sure to add that Halloween touch to any aquarium large or small.

They’re actually cool enough to leave in all year round. Just make sure you get permission from your Betta!

Zombie Grave Decoration

We have a lot of Halloween on this list, but it’s the most fun to decorate for, right?

Place this Zombie ornament anywhere in the fish tank and achieve optimum spookiness.

That’s not all…it’s glow in the dark, too!

Day of the Dead Skull

If you’re celebrating Dia de los Muertos, this skull ornament is a great grab.

The bright hot pink will definitely stand out. Along with any decorations already in the home, this will be a really cool addition.

Your fish will be pleasantly surprised!

Santa Underwater

Christmas is the time for decorating. Get the cute underwater santa from PetSmart and get festive with the holidays.

Nothing says Christmas like Santa, so get your fish into the holiday spirit with this adorable ornament. It’s also a fun addition for guests when they look into the tank and see a little surprise.

Walrus Ornament

If you can believe it, this adorable new addition to your fish tank is under $2.

Yet, it’s so festive! The Holiday Walrus Aquarium Ornament is great for holiday spirit in any fish habitat. It’s only three inches in height, so it should be in any fish tank in the house.

Bring it out every year for a little Christmas cheer!

Time to Get Festive

Who knew fish tanks could be so festive? If you’re a decorations person, you know the details are what matters. Take pride in your fish tank, aquarium, or even your terrarium by spicing it up for any holiday.
