Best SpongeBob Themed Fish Tank Decorations

Considering he already lives in a pineapple under the sea, SpongeBob is an excellent choice for a fish tank. Today’s article will cover all of the best SpongeBob fish tank decorations. I will also include photos of all the ones I bought and put in my SpongeBob themed fish tank.

Best SpongeBob fish tank decor

The best SpongeBob themed fish tank will need the popular landmarks, the 6-piece character set, and bright plants. You should also have a sand or coral substrate.

Popular landmarks

While you don’t need all of the popular locations of Bikini bottom, there are a couple mandatory decorations. You will need SpongeBob’s pineapple, Squidward’s house, and of course the Krusty Krab. I also suggest that you get Plankton’s chum buckets, as it is also a staple in the show.

I was able to find all of these buildings for sale on amazon for around $10 each. They are all made by Penn-Plax, which is the biggest fish tank ornament brand on the market.

There are also other spongebob fish tank ornaments on Amazon including Bikini Bottom homes and the bikini bottom bus. While there isn’t an exact rock that matches Patrick’s house, there is a coconut aquarium ornament that is a good alternative.

SpongeBob characters fish tank ornaments

The best SpongeBob character fish tank set is definitely the Penn-Plax 6 piece ornament set. It has the 6 main characters from SpongeBob. They are a great addition to put in front of the famous SpongeBob landmarks.

It includes SpongeBob, Patrick, Squidward, Sandy, Mr. Krabs, and Plankton. These SpongeBob fish tank decorations are made of resin and safe for both freshwater and saltwater aquariums.

Best of all, this ornament set only costs around $10 on amazon. They are a great option if your are looking for bright glofish decor.

Best plants for a SpongeBob themed fish tank

I recommend that you use bright, fake plants for your SpongeBob themed fish tank. While you can use live plants, it will require more maintenance. Also, live plants usually are not as bright as fake plants, especially live freshwater plants.

A great option for plants is this Comsum 10 piece plant set, which you can get for only $6. They resemble a lot of the plants in Bikini Bottom.

These plants range in heights from 4 to 4.5 inches. While this might seem small, I prefer to have smaller plants so that they don’t tower over the other ornaments.

However, if you are looking for taller plants, you can check out this set.

What substrate should you use for a SpongeBob themed fish tank?

The two best substrates that you should put on the bottom of your SpongeBob aquarium are crushed coral and sand. While sand might look the best and resemble Bikini Bottom more, I prefer crushed coral.

This is because crushed coral is much easier to maintain. Since it is heavier than sand, it will stay rested on the ground. Sand will get pushed around more, especially if you have a strong filter. This can make your fish tank very cloudy. Crushed coral also helps maintain the pH balance of your fish tank water, which is another reason why I prefer it.

Best fish for a SpongeBob fish tank

Since SpongeBob fish tank decor is pretty small, it is best to have smaller fish in your tank. Smaller fish will be able to swim around and within the ornaments without getting stuck or knocking them over. Glofish are a great option because they will match the bright, vibrant colors of the decor.

Conclusion

I hope this article gave you some good SpongeBob fish tank ideas. Most of these SpongeBob fish tank decor items are very cheap and can be bought on amazon. If you are interested in other shows or movies, check out my article on the best movie themed fish tank decorations.
