Sims 4 Aquarium & Fish Tank CC + Mods (All Free)

Fish are the definition of chill. Spending their days floating around with not a care in the world.

Our Sims can’t be fish (well, not yet) but we can get an aquarium to love them! Yet not every Sim can handle the responsibility of aquarium upkeep (this is why aquarium channels exist).

Cats and dogs? Yeah, a little easier. But fish deserve more.

That’s why we’ve curated a huge list of free fish tank CC that’s well worth browsing. Just to add a bit more life into your Sim’s fishy home.

It’s a fish eat fish world out there.

But don’t let your precious guppy know that when you put it in this aquarium by Mia8.

This fish-shaped fishy home is just that: an aquarium shaped like a fish. It’s a clear tank, shaped like a fish with the mouth as the opening, resting on a rock slab with pebbles and some leaves on the side.

It fits one fish that will be happily swimming, blissfully unaware of life outside his new aquarium. A fishception, if you will.

The famed Koi, carps who originate from Japan, represent good luck and abundance. That representation might be one of the reasons why these fish are so expensive!

But fret not. You don’t need to be a Simoleonaire to have a Koi aquarium.

Bakie’s custom Koi Fish Group CC contains 6 animated Kois that actively swim around. Whether you have a zen garden or a tank, these fish add a touch of opulence to your TS4 home.

We love creator Mia8’s penchant for naming her CCs as obvious as can be, so you already know what this is!

House your small fish in this aquarium shaped like your run-of-the-mill kettle. It is transparent, so you can observe how the fish acclimates to life in a kitchen pot.

Just remember, this water is not potable!

If you’ve ever been to an aquarium, you get the gist of this one already.

A room filled to the brim with marine life and kids tapping glasses at every corner. Those kids are usually followed by parents are excited by the fact their kids will be knocked out on the way home for the rest of the day.

One of my favorite things to see during trips to aquariums are wall-to-wall tanks.

If you love those too, then why not add them into your home with SpaceSims’ Maia Aquarium?

This giant tank mod with a modern look will give your Sim’s house the aquarium feels, without kids running around in the background!


11. Guitar Fish Tank

Fish tanks shaped like other things seems to be a popular choice here.

Merge your love for music and the aquamarine with the Guitar Fish Tank mod by Xelen.

This is part of a Mexico-themed set, inspired by those El Mariachis, but can be downloaded separately with other guitars packs.

Perfect for musical virtuosos and failed country singers!

A fictional private detective once said, “Be careful what you fish for”.

And he’s right. Cause you would want to display your most fabulous fish using this aquarium created by DavinaOjeda.

There’s nothing elementary about this tank. Giving you total steampunk vibes reminiscent of Sir Arthur Conan Doyle’s universe, this elegant aquarium will go great in a grand hallway or library.

There are lots of fish in the sea, but not all of them can be caught.

Yes, we’re literally talking about fish. Please direct your dating concerns to the appropriate channels.

Bakie Gaming’s Placeable Fish – Pack 1 features twelve different fish species that aims to give your simulated marine life some diversity.

Now if that’s too many, you can also change the amount of fish. These little swimmers are placeable in oceans, pool aquariums, and empty room aquariums.

Is your Sim a budding fishkeeper? Hone your skills with RAVASHEEN’s Sofishticated DIY Mini Aquarium.

This starter aquarium CC might be one of the simplest options on this list. But we give it plus points for the punny name!

This is a set containing 8 items with decorations sure to give life to the tank, including sand and corals, to simulate your gilly friend’s natural environment. It’s also totally customizable!


7. Dine Out 6 Fish Aquarium

Are you like modder LittleMsSam who can’t get no satisfaction from the Dine Out expansion’s Fish aquarium… mostly because it features too few fish?

She’s here to save the day with the Dine Out 6 Fish Aquarium mod that brings the fish count up to 6 using the fish purchase picker menu.

Your Sim might need to stack up more on fish nibbles, but at least the tank will feel less empty.


6. Love Swan Fish Tank

Love Swan Fish Tank for Sims 4

Check Out This CC

Ever wonder why boats in the Tunnel of Love are mostly shaped like swans?

Swans, after courtship, mate for life.

I wonder if their vows also say “til death do we part”?

Show your Sim’s undying devotion to their paramour (at the same time gauging their capability to take care of a living thing) with this Love Swan Fish Tank.

Created by PetSimK, this tank is shaped like a swan with the neck curved downward.

When you put two head-to-head with each other, it will form a heart shape enough to make you believe in true love.


5. Koi Fish Aquarium

Zen homes are a popular style, both in The Sims and real life.

An oriental home style has seen an uptick lately, maybe driven by the human desire to achieve inner peace.

If koi ponds aren’t your thing, take a look at this Koi Fish Aquarium by Bakie Gaming, who seems to be a ‘fishthusiast’ with all the related content!

This aquarium CC is as minimal as it gets, with two herons drawn at the bottom half of the tank. Not to worry, these herons won’t be able to munch on the 5 Kois you get with the tank. A perfect view while you complete your “ohms”.

Note: the Spa Day game pack is required here, which is a prerequisite if you want to achieve total nirvana.


4. Placeable Fish – Sharks

We’re going to say something controversial, yet totally brave: Jaws was not the villain of the story!

Sharks get a bad rep as bloodthirsty creatures. But they rarely ever kill humans.

There are more deaths by coconuts falling on people’s heads. Seriously, look it up. We’ll wait.

Are you a sharks fan like us? Convert your boring old pool to a shark aquarium with another one of Bakie’s creations, the Sharks CC pack.

It comes in 8 swatches, each with different formations of sharks who won’t hurt your Sim in any way!


3. Globe Fish Tank

Even though they can’t understand us(unless you’re Aquaman) fishkeepers sometimes love talking to their pet fish.

Call it an expression of love or gaping loneliness, (which let’s be real here, is kinda correlated) it’s undeniably a great way to feel connected!

But what if those gaping mouths could respond?

PetSimK’s Globe Fish Tank mod allows just that!

If your Sim is a mermaid, you can finally discuss your plans for evil domination or world peace in a way that your roommates just can’t understand.


2. Under The Sea IV: Marine Fishies

Darling, it’s better down where it’s wetter. Take it from me!

This Marine Fishies pack by Snowhaze features 10 colorful varieties of fish made for TS4.

They’re perfect if you’ve converted your swimming pool to an aquarium, with underwater bubbles for a dose of realism. If you want to be like Ariel and swim with them, they won’t be a nuisance because they reside below the level of swimming Sims in the pool.

Sadly, there’s no singing lobster that will judge your every move included in this pack. Maybe in a future update.


1. Aquarium Counter Island Base

Aquarium Counter Island Base Sims 4 CC

Check Out This CC

Let’s end this list with a classic dual-purpose aquarium that will suit any modern home from Willow Creek to Newcrest.

Snowhaze’s Aquarium Counter Island base gives the aquarium more purpose than housing fish.

With four counter spaces, you can use it to place another aquarium (again… fishception!), you can put your kitchen appliances on top, you can even put your sink on it!

Not exactly sure if that’s safe… but it sure looks cool.
