It’s October! Time for witches and werewolves, ghosts and goblins.
Your social media feed has likely been taken over by Halloween-themed memes, posts recommending the best costumes for the family and polls asking which candy is your favourite.
Here on Shed Happens, we have also been jumping on the spooky bandwagon.
Recently, I have shared posts describing the best Halloween costumes for large dogs as well as some recipes to make your own Halloween dog treats.
However, the Shed Happens community has always been about celebrating ALL pets, not just dogs!
So, that had me digging into another group of the pet loving community.
According to a survey released by the American Pet Products Association, there are approximately 11.5 million households that own freshwater fish, while another 1.6 million are saltwater fish owners.
While these pet owners aren’t dressing up their pets for Halloween, fish owners can celebrate Halloween too!
I have done some digging (and online shopping) for fun, spooky and adorable Halloween-themed decorations to create the perfect spooky fish tank.
Confession: I have been slowly putting together a wishlist for my own fish tank in the near future…
If you’re looking for Halloween decoration inspiration for your fish tank, you’ve come to the right place!
Spooky Fish Tank Inspiration for Halloween Lovers
Nothing Says Halloween Like A Skull
When it comes to spooky fish tank decor, you can’t go wrong with a skull.
This fun piece not only acts as decoration, bringing that creepy vibe into the space, but it also provides your fish with a new hiding place.
At just over 5” deep and 4” tall, it’s big enough to make a statement without taking up too much space in your tank.
A Skeleton at the Wheel
It’s time to introduce a new captain to your tank, and this one is here for the long hull!
This fun decoration shows a skeleton pirate, sporting an eyepatch, standing at the wheel of his ship.
Looking to take it to the next level?
Your skeleton also works to provide aeration with the use of an air pump PLUS the air drives movement in your new decoration, with the wheel turning as the captain steers his ship through the depths.
Glow in the Dark Accents
Don’t just decorate your fish tank for the daylight… Adding some glow in the dark accents will carry the spooky fun long into the night.
The easiest way to add a glow in the dark touch would be to purchase glow stones for the bottom of your tank, but that isn’t exactly the ‘spooky’ way of doing it, is it?
Instead, bring in the glow with some creepy zombie hands!
Add Some Adventure
Do you want to take your fish on a creepy adventure this spooky season?
Try introducing a new scary location to their tank like this creepy Skull Mountain.
Your fish will have fun exploring the new hiding spots while adding some spooky décor to the space.
Embrace the Cute Side of Halloween
Are you not totally sold on the spooky, creepy side of the holiday?
One of the great things about Halloween is that there is something for everyone – spooky, gory, scary, cute…
This adorable pumpkin house will add a touch of Halloween spirit while aerating your tank with air bubbles rising from its chimney.
Cute little jack-o-lanterns and a skull in a top hat will complete the look.
Don’t Forget the Jack-O-Lanterns
Nothing says Halloween like jack-o-lanterns.
I mean, is it even spooky season without the grin of carved pumpkins staring back at you?
You can’t drop a real pumpkin into your fish tank, that wouldn’t end well for anyone.
However, these adorable resin pumpkins will do the trick!
Add A Spooky Background to Complete the Look
I have always loved the way that an aquarium background can transform the look.
The best part? They are incredibly easy to use, clinging to the back of the fish tank on the outside.
This means that you can change them up with each season if you feel like it!

Fish lovers, have you included your aquarium in your decorating plans?
What are your favourite ways to create a spooky fish tank this season?
I am a fish keeper and it’s a pain sometimes but decorating/scaping the tank is ALWAYS the best part of being a fish keeper. That, and happy fish. I have been on the lookout for some skulls as my Petsmart doesn’t have much in that style and I’m so in love with some of the ones you chose to share with us! Thank you! By the way, I have some pet posts on my blog in case you want to check them out 🙂 tidbitsofcare.com
I am ALL about skulls – Our whole house is decorated in skulls and Nightmare Before Christmas lol! I am currently looking at setting up a new fish tank (I want a betta in my home office) and I’m scoping out which skulls I want to include lol
The skull looks really cool if you run a smallish bubble stone inside it- bubbles out the eyes. The skull mountain is fun too. I only had a 5 gal tank for a betta but we used both the skull sets to decorate the tanks in the store I used to manage. I wish we’d had the pumpkin house, that would have been fun to design a tank around.
I love that idea with the bubble stone! I’m in the process of getting everything for a betta in my office. It’s also a 5 gal tank. I’m going to have to put this idea to use!
This is so creative Britt, I never would have thought of this! I especially love the skeleton pirate captain and the glow in the dark zombie hands! Those combines with the full moon/bat background would make a fantastically festive fishtank!
Right? Use a black aquarium stone for the bottom with a few glow in the dark stones mixed in – I can picture it!
