Guppy Tank Decor Ideas

Guppy Tank Decor Ideas:

Once you have decided that you are going into the hobby of guppy fish then you have some exciting work ahead of you.

Your first priority is going to be in setting up a safe environment for your guppy fish.

At the same time, you are going to want this to look attractive especially if it is your first tank.

If you are only going to maintain one tank then you probably want to have this on display in your home.

For those that are going to keep guppies simply because of the visual enjoyment they provide then these tips for setting up the decor in your guppy tank will be useful to you.

If you are into the guppy hobby because your intent is to breed them, then the decor will not be as important to you.

In this case, you are going to need a few tanks and you are not likely going to have them on display in your home.

Cool Aquarium Decorations for Guppy Fish Tanks

There are many different accessories that you can use to enhance the look of your fish tank.

Moreover, you can actually decide to set the theme for them based on the decor that is available to you and to enhance the ambiance of the room of your home where the tank is going to be placed.

guppy fish Aquascaping

Those that are really focusing on the visual appeal of guppy tanks are participants in aquascaping.

Is Aquascaping Good For Fish? This is where the tank only houses a small number of fish and the real focus is placed on the visual presentation of the tank itself.

Those that are using guppies as their chosen fish species in aquascaping, will choose those whose colors enhance the overall decor of the tank.

For those that are just content to have a nice-looking tank for their guppies, they focus on creating a natural-looking environment using as many natural products as possible.

These include the aquarium plants as well as the rocks and stones and other ornaments that mimic what would be found in the natural habitat of the guppy.

It can get quite expensive buying all of the decors that can be used in the aquarium so you may want to set a budget for this.

Live and fake plants for Guppy Tank Decor

Live plants can be quite expensive and you do have the alternative of going to artificial plants, however, you want to be really careful as to the quality of these.

Those that you buy at your aquarium store are specifically designed for the aquarium setting.

Some individuals like to go to discount stores and pick up different types of artificial foliage.

The concern here is that they may contain toxins that could be detrimental to your guppies.

The one thing that you have to keep in mind when you are choosing live plants is that they have requirements as well and you must make sure that their requirements are going to be compatible with your guppies. 

Feeding you guppies

If you are keeping any plants in your aquarium you should feed them as they quickly use what they need from the water.

You can buy aquarium plant food in most pet stores and they can come in liquid or solid that is buried under the gravel.

You can also use dried rabbit feces and push a couple of pellets in the ground near each plant!!

Lysimachia nummularia (Aurea)

This plant grows both on land and in aquariums. On land, it spreads out as ground cover with a yellow flower while in water it grows upright and tall.

This is a very beautiful plant with its leaves small and rounded in its shape opposite each other on each stem.

It is very easy to keep in aquariums as it is very undemanding.

It seems to do well in most if not all light conditions and water chemistry doesn’t seem to play a part.

This plant comes in a green and an almost yellow/ light green color.

It makes a great addition to any aquarium and grows tall enough to grow in the back to cover the glass or a filter!

Once your aquarium is decorated, it will look like your fish are living in an aquatic 5-star hotel resort!

Besides great plants, there are all kinds of funny furniture and toys you can add too, according to your taste.

Lemma Spp (Duck Weed)

This is in my opinion a nice plant for any aquarium although a lot of people don’t like it.

It is a fast-spreading plant and is often introduced in a tank accidentally with another plant.

Duckweed grows very well with a lot of light but if it’s not kept it can quickly take over and block filters!

It is a great plant to use for bubble nests as it floats on the surface of the water.

This plant can grow tall but I find that because the stems are so weak the fish eat them across so they stay pretty low down if that happens.

Vallisneria gigantea (Giant Vallisneria)

This plant is ideal for a tall aquarium as the leaves can grow up to 40 inches long!

When the plant reaches the surface the leaves then float along the surface and not out of the water.

As a result, this plant can be used for fish to build bubble nests.

This plant grows in cycles: 3-4 months of good growth and then starts to dye off but then grows again.

They like a fine substrate to grow in like sand or fine gravel.

These plants thrive if there is iron present in the water’s lower levels and in the gravel.

Microsorum Pteropus (Java Fern)

This plant is easy to grow in any aquarium.

Its tough roots will attach this plant to rocks and bogwood but it can also be grown in the substrate.

Lighting is not critical for this plant and nor are the water conditions.

This is a very decorative plant with long leaves which in time sprout new plants at their tip.

When the leave rots the new plant floats away and it could grow on any surface in your aquarium!

Microsorum Pteropus (Java Fern)


Algae grow in all aquariums and on every surface in them! You can get fish to eat algae and you can also get “medication” that kills it in your tank.

You can get cleaning stuff to take it off of your aquarium glass too. recently I found out that hydrogen peroxide (H2O2) can be used to kill hair algae.

Bottles can be bought in most chemists at a 3% volume and this is added to the tank at 1-1.5 ml per 30ltr.

You can add it using a syringe and spray it onto the algae or just put it in the tank.

After a couple of days the algae breaks down and the fish will eat it off of most surfaces and the peroxide also helps stop it from spreading again!

It should not harm your fish or plants unless you overdose the tank so be very careful.

Cycling of Tank for Guppy Tank Decor

They do help with the nitrogen cycle for the tank but they have to have a specific amount of lighting.

For this reason, you might want to start out with the artificial aquarium plants until you become more familiar with maintaining guppies.

You can also look at rocks and stones and glass ornaments that are made from many different materials but again be sure that they are not going to contain any toxic components.

For your fancy guppies when using these larger items they are better situated on aquarium sides.

Rather than taking up all of the middle space as the fancy guppy prefers to have room to move freely.

In summary

Once you have decided on the decor that you’re going to use,

then how it is situated and how you set it up is going to take a little bit of planning on your part.

The key here is not to overload the tank with decor but just add enough, that it creates a nice healthy atmosphere for your guppies and also creates a pleasant look as a beautiful addition to your home atmosphere.
