Do Guppies Like Caves? Top 3 Things You Should Know!

Do Guppies Need Caves?

A cave is not necessary for guppies but it is preferable since it gives them places where they can hide. A hiding place not only allows the guppy to have a place to rest but also makes them feel comfortable during the breeding time.

Note that a cave is not an absolutely necessary thing for your guppy. If you feed your guppy properly. If you give it enough space to live in the tank and in a calm environment without any competitor or other tank mate chasing your guppy, then it will be okay for your guppy to live.

However, note that having a hiding place such as a cave in your guppy tank can be definitely a good thing.

1. A Cave Allows Your Guppies To Hide When They Are Stressed

If for some reason your guppies feel stressed then they can just hide away in the cave. Remember that, hiding is a natural instinct for fish. More hiding places allow the fish to feel more secure.

So if your tank has enough hiding places made using caves, driftwood, plants, etc. your guppies can feel secure.

2. A Cave Gives Protection To Your Guppies If Attacked

If some guppies in your tank dominate, fight and chase other guppies. Then in that case having a hiding place becomes a must, right?

Hiding places such as a cave will offer a visual break in your tank landscape. So your guppies can move around more freely in the tank and whenever they get chased, they can just immediately hide in the cave and thus protect themselves.

And not just other guppies, but if you have other tank mates then sometimes they may also get aggressive and chase some of your guppies. So having a hiding place becomes a must in that case.

How To Setup Caves In Guppy Tank?

If you have a rectangular type long tank and you are only deciding to put a cave or two in your tank then I would suggest you put that in the center of the tank.

Why? Well, it is because it will be a good attraction for viewers watching your guppies coming out and going inside the cave right at the center of the tank. Your kids will enjoy it a lot watching your guppies.

If you put it in the corner of the tank then also it is okay. But generally, the central part of the tank gets viewed more, because it is straight in front of the vision whenever we view the fish tank, right? And so I would advise you to place it there.

However, if the center part of your tank is already covered because of plants or any other type of setup then obviously you can place it in the corner of the tank.

Now regarding what type of cave should you have in your Guppy tank. You can have the normal cave design toys which are made from rock. You can also select some unique cave designs to make your guppy tank look different and beautiful.

You can select the various designs and sizes depending on the tank size and setup you have

Here are some of the ways you can make caves in your Guppy tank:

1. Using Rocks

If you like a natural look in your tank then creating cave-like hiding places using the rocks can be a great idea for you.

When you place the rocks properly inside the tank then they can create the cave kind of structure by providing space in between the rock structure.

However, it is important to carefully set up the cave using the rock structure because you, at last, you won’t like any kind of accidents like a rock falling on your guppies, right?

2. Using Driftwood

A Driftwood is another great option to create a cave-like structure in your aquarium. It will also provide shelter to your guppies within the gaps and caves that naturally occur when you place the driftwood in your guppy tank.

3. Using Pots

Get it here (on Amazon)

You can also place pots in your aquarium and it can also provide the cave-like structure in your aquarium.

As per, the pots to use are called clay or terra cotta pots.

So you can use these pots to make cave-like structures in your guppy tank. You have to actually be a little creative here.

There are also some important things to remember while using the pots.

Make sure that the pot used to make the cave structure for your guppy tank is not painted or dyed, because it can contain harmful chemicals that could leach into your tank.

Try to select the new pots if you are selecting a pot for your guppy tank from your garden because old and used pots might have already been exposed to chemicals and fertilizers.

Make sure that the pot is smooth from everywhere because at last, you won’t like it if your guppy gets hurt because of any sharp or pointed edge in the pot, right?

And this is probably the most important point. If there is a drainage hole in the bottom of the pot (which will be there in most cases) then please do something about it. Although your guppies might be small enough to pass through the drainage hole in the pot. But still, prevention is better!

It can happen that you wake up in the morning the next day and find that your guppy is stuck in the hole or got hurt while getting out from there.

So you can remove the entire bottom of the pot and then use it to make caves in your guppy tank. Alternatively, use aquarium safe glue to close the holes with rocks or seal them with silicone.

Where To Get Caves For Guppies?

You can get caves in any of your local pet stores. You can just ask them about the aquarium toys and caves and they will show you the toy caves of various designs.

You can choose the design that will suit well with the overall look of your tank. Generally, the more natural look you can give the better it will be isn’t it?
