The great thing about a SpongeBob SquarePants theme fish tank is that you can use your own creativity to set the characters out just as you wish. You could have all the characters near each other, interacting in some way, or spread out throughout your tank.

If you have fish and animals that like to hide, make sure you get the houses and restaurants from the show. Spread these ornaments out in the tank rather than setting them up close to each other so that your pets can set up their own territories.

If you watch the show, In most cases the ground is a yellowish color, so you could use yellow gravel for the floor of your tank, and even make your own roads between the buildings out of dark grey gravel, just like in the show.

When setting up a SpongeBob Squarepants theme aquarium, it is important to remember the basics of maintaining a healthy fish tank. Make sure you have a good filter and a heater in your tank to keep the water safe and comfortable for your fish.

Frequently Asked Questions

Can you use aquarium decor for snakes?

You can definitely use aquarium decorations in your snake enclosure. Snakes also love to hide in caves just like some fish do, so don’t be surprised to find your pet snake curled up inside a cave ornament or even SpongeBob’s pineapple house.

What can I use to clean my fish tank decor?

Most fish tank decor is beautifully hand-painted and to be on the safe side, you should only use a soft brush to clean them so that you don’t scratch the paint. An old toothbrush makes a great brush for cleaning your ornaments.  It is better to use only water, and no soap,  while washing them because you don’t want to add any harsh chemicals to your aquarium that might harm your fish.

Should I clean my fish tank decorations?

You don’t have to clean your aquarium decorations, but they probably will get dirty in time. Algae might start to grow on them, covering up the colors and details. To keep your ornaments looking colorful and clean, wash your ornaments regularly. Another thing that can really help to keep your SpongeBob ornaments clean is to keep algae-eating animals in your aquarium like Amano shrimps, Otos, or Siamese algae-eating fish.

Where to buy aquarium decor?

You can buy aquarium decor online or from your local pet shop. Amazon.com is a great place to shop for new aquarium decor because they have such a great variety and you can have your new ornaments delivered to your home. Portland aquariums have put together the best collection of aquarium decor on Amazon, from sunken ships to cave decorations that you can choose from.

Can you bleach aquarium decor?

Bleach will work to clean aquarium decor but its use is not recommended for colorful ornaments like SpongeBob decor. The problem with bleach is that while it does clean your decorations, it also tends to cause colors to fade, and your SpongeBob decorations will look their best when they are bright and colorful.
