23 Goldfish Tank Decoration Ideas To Enhance Your Aquarium

I'll be going through some great goldfish tank decor ideas to give you some ideas and inspiration. I'm sure there's something here for everyone, whether you want a Star Wars theme or a princess castle, I've got you covered!
Goldfish tank decoration ideas

When it comes to decorating your goldfish tank, you should always do so with the safety of your goldie as the foremost priority.

Take into account the size of your goldfish before choosing decor items, either choose items that are too small for your fish to fit inside or choose something with plenty of space.

Goldfish are inquisitive guys, but let’s be honest, not the most intelligent! The last thing you want is for your fish to become stuck or wedged in the decor.

Goldfish Tank Decoration Safety Tips

If you keep fancy goldfish with protruding eyes (black moor, butterfly tail, celestial eye, etc.), I’d avoid adding decorations as they can very easily damage their delicate eyes, less is more with these little guys.

Check all items for rough and sharp edges and points that could injure your fish or tear their delicate fins. Make sure these get filed flat and smooth.

Check for any loose parts. Goldies are inquisitive and love to peck at everything. Anything loose may be picked off and present a choking hazard.

Beware of cheap imported plastic ornaments that may leach chemicals into your tank water and poison your fish.

Smaller decor items can be glued to larger items, rocks, or driftwood, to stop them being moved around by mischievous goldies!

Wash all decorations (and rinse thoroughly) before adding them to the tank.

Aim to keep at least 75% of the tank space free for swimming.

Now I’ve geeked out a little, I’ll move on to the more traditional types of decorations.

13. Bridges

These have to be one of the most popular options for decor ideas, there’s a style to suit everyone.

If you’re after a little piece of NYC the Brooklyn Bridge is ideal, for a more rustic pirate-style tank the Plank Bridge will look great, and for a more natural look, you can choose either the Arch Bridge or Arch Bridge with tree pavilion.

My Moby would spend all day swimming under his bridge until he got too big for it.

14. Sunken Ships

Who doesn’t love a sunken ship decoration?! I love anything to do with the Titanic, so that would be my choice.

If a Battleship, Pirate ship, or Submarine is more your style, there are some realistic-looking options to choose from that will make a great centerpiece in any tank.

15. Sunken Aircraft

For military aircraft fans….

Whether you prefer a Helicopter, an Allied WW2 plane, or a Nose-dived fighter plane, any of these 3 will look awesome!

16. Divers

A great feature of some of these diver decorations is that you can connect an air pump to them, which not only looks great but oxygenates the water too.

17. Skulls

If skull decor is your thing, you’re spoilt for choice, just be sure to file down any sharp points.

Choose from a Crocodile skull, Dinosaur skull, Human skull, Rhinoceros skull, or a Triceratops skull to create the look you’re after.

Who doesn’t want a Rum drinking pirate skeleton in their tank?! Add an air pump to watch him drink all day long!

Alternatively, you can have a skeleton at the wheel, swaying side to side as he steers what’s left of his sunken ship.

19. Castles

A castle is a must-have addition to your aquarium to create that magical feel.

20. Cars & Van Wrecks

I’m a petrol head so naturally I’m drawn to some of these, It’s a shame there are no Mustang ornaments.

Closing Thoughts On Goldfish Tank Decoration Ideas

I hope I’ve given you some inspiration for decorating your Goldfish tank, the choices are practically endless.

Just remember to keep the safety of your goldie in mind when buying decorations:

  • Consider if your fish could get stuck/wedged in the decor item
  • Make sure the item isn’t so small that it becomes a choking hazard
  • File/sand down any sharp points
  • Check for any loose parts
  • Smaller decor items can be glued to larger items or rocks
  • Wash all decorations before adding them to your tank
  • Keep at least 75% of the tank space available for swimming

Check out the aquarium health section for guides on keeping your aquarium in tip-top shape.
