Best Rocks For Cichlid Tank: Top 5

Cichlids are some really beautiful tropical fish no doubt. You may have heard people talking about rocks for Cichlid tanks. Well, this is because rocks are an integral part to a happy Cichlid community. They use rocks for play, to get cover from other fish, for privacy, and for spawning young fish too so it’s important to get the best rocks for your Cichlid tank possible.

Some good rocks will make all of the difference in your Cichlid tank. However, the hard part is finding the right rocks (this is our top pick). This is a little tricky as there are many options to go with, but that is why we are here. We’re going to talk all about rocks for aquariums and for Cichlid tanks specifically, as well, we have the top 5 Cichlid rock options for you to take a look at.

What Kind Of Rocks Are Good For Cichlids?

This question is somewhat hard to answer as it really depends on the area in which you live, the types of Cichlids you have, and what materials you have access to. Anyway, let us do our best here. First and foremost, fake rocks work just fine. Don’t worry about getting real rocks if that is not your thing. Treated ceramic rocks will work just fine, especially if you find them at a pet store. However, you can of course get real rocks too, but you have to be careful with what you select.

What is important to note is that there are different Cichlid species, which implies that they do have different requirements. For instance, African Cichlids do well in waters with high calcium and mineral contents, or in other words, in hard water. This means that rocks with a high mineral content will do just fine. On the other hand, Cichlids from South America need softer water, which means that those kinds of rocks will not do.

Simply put, pretty much any kind of rock will do just fine in your Cichlid tank, depending on the type of Cichlids you have. What does need mentioning is that super crumbly rocks will not hold up long as they will disintegrate in the water. At the same time, things like volcanic rocks and ones that contain lots of metal will not do either.

Those will pollute the water, plus they can have some really sharp edges that hurt the fish. So, when choosing real rocks for your Cichlid tank, make sure they are soft enough to be safe, hard enough to actually last in the water, and have the right mineral content in order to keep the water parameters stable and ideal for your inhabitants.

On a side note, anything from an art store, such as painted rocks (not waterproof) or anything with sparkles is a big no-no. For example, normal bricks made will do just fine (as long as the edges are smooth), while concrete chucks will definitely not do. The best way to go is with a smooth but hard rock that does not contain too many minerals and minimal (ideally no) heavy metals. All of that being said, Cichlids love caves where they can hide in, so anything in the form of a cave is very beneficial.

What We Think Are The Best Rocks For Cichlid Tanks

In our eyes there is a clear winner here and yes it is a fake rock. The takeaway here is that you might never know exactly what real rocks contain, especially when you find them yourself. A nice fake rock is a perfect way to go in order to ensure the safety of your Cichlids.

MF CICHLID STONE Ceramic Aquarium Rock Cave Decor

This is a ceramic rock cave for your Cichlids. It is not only for Cichlids, but they will certainly love it (you can check the price and more info here). It has a smooth surface that can act as a good breeding ground for your fish, both on the inside and outside. The cave itself is fairly large and will easily accommodate several Cichlids, making it perfect for breeding and spawning. It makes for a really nice smooth and natural environment, the same kind which these fish would have in the wild. This item will make for good shelter for all of your fish, shrimp, and even snails too.

It is a 100% ceramic rock, not a real rock. It is a surprise that a fake rock like this looks as real as it does. You really can’t tell the difference between this thing and a real rock. It has been treated and tested for safety in order to ensure that it does not leach chemicals into the water. It is quite convenient that this cave is hollow because it does not displace too much water in the aquarium, therefore it is technically a space saver. The rock itself is a little too small for other fish though. Only smaller fish like Cichlids will be able to make good use of this thing.

4 Other Rock Options That We Like

Not all people have the same tastes or needs, which is why we have another 4 awesome Cichlid rock options for you to check out right here.

1. Carib Sea Sea Base Rock Bag

This is a very simple yet effective rock option to go with for your Cichlid tank (you can check the price and more info here). It is taken straight from the Caribe South Sea, right off the base. In other words, this is a real and natural rock, just like Cichlids would have in the wild. Some people definitely prefer having real rocks, in which case this makes for a fantastic option. This is an awesome rock for growing coral in fact. It has a fairly rough exterior which makes it ideal for coral and algae to take hold, which is something that many people like about it.

What is also neat about this rock is that there is no curing needed for it. You can put it right in your aquarium as soon as you get it. It is safe, not dyed, and will not leach any poisons or chemicals into the water. What does need to be said is that this is a big and heavy rock, so it will displace a fair amount of water. There is also the fact that this is just a rock, not a cave, something which Cichlids may or may not like.

2. Small Slate Rocks

Now, these are technically not rocks intended for aquarium use, but they certainly can be. They are made of slate brick, or in other words, it is naturally occurring. These particular slate rocks have been water tumbled to make them smooth and to remove sharp edges from them. This makes them safe for your fish. The rocks themselves are low in compounds and minerals, plus they are not dyed, so they won’t pollute the water in any way.

They come in a variety of shapes and sizes, making them beautiful addition to a Cichlid tank. Moreover, they are not too big or heavy either. In fact, you could use some aquarium glue to paste them together into a cave for your Cichlids to enjoy. One thing that does need to be mentioned about these slate rocks is that they are a little bit on the soft side, so if you have a tank with lots of water flow, they will very slowly break off.

3. Nature’s Ocean Coral Base Rocks

One of the best parts about these rocks is that they come right from the ocean. They are naturally found on the ocean floor, making them perfect for the floor of your tank. They are very coarse and have lots of naturally formed holes and crevices. This makes them ideal for algae and coral growth, something which many reef tank owners definitely want. The rocks are also very porous, which means that they are good for the growth of bacteria, or in other words, the provide you with a great natural biological filter.

Their unique shape and rough pattern also makes them easy to stack on top of one another, making them perfect for nano reef tanks. They have been soaked in a special solution and treated properly in order to make sure that they do not leach any harmful chemicals or minerals into the water. All of that being said these rocks are pretty big and heavy, so they will displace a fair amount of water in your tank. While these rocks don’t actually come in the shape of a cave, you could certainly use some aquarium glue to achieve that look.

4. Large Decorative River Rock Stones

These are nothing more than naturally occurring basic river stones. They are not too large and they are round. On one hand, their shape does not make them ideal for stacking, but with some glue, you can make virtually anything with them, especially a cave that your Cichlids will love.

These rocks are very hard so they won’t crumble in the water, but thanks to being tumbled river stones they also don’t have sharp edges. While these rocks are ok for a section of the tank floor or for some decoration, they are not ideal for any kind of coral or biological growth. One good thing about these rocks is that they definitely will not leach any chemicals into the water.

Can I Find & Use My Own Rocks?

You can definitely use rocks that you find, but you do need to keep the above considerations in mind when doing so. First off, when you find a rock, try to identify what kind of rock it is. You can use the internet, go to your local fish store, or get a geologist too. The point here is that the type of rock will determine what kind of mineral and metal content it has.

Minerals are one thing, and water hardness is OK for Cichlids like African Cichlids, but you definitely don’t want a rock that has a high heavy metal content. Heavy metals are poisonous to fish just like they are to us. So, a rule of thumb is to never take rocks from an area known for mining or from rivers known to be filled with metals or factory pollutants. For instance, rocks that contain a lot of iron can rust, and while rust is usually inert, and will therefore not poison the water, it will turn it orange.

If you find your own rocks, hose them down while scrubbing with a stiff brush to make sure that they don’t flake apart. Also, rub your hands along the rocks. If they are too sharp for you to apply pressure with your fingers, they are too sharp for the fish. The point is that you can definitely use your own rocks that you find. However, before you put them in the tank, you need to clean them.

Best Way To Clean The Rocks I have Found?

The easiest way to clean rocks for your aquarium is by using a bleach solution. Make a bleach solution of 1 part bleach and 9 parts water. Soak the rock in that mixture for several hours. After you have done this, use some chemical free soap and hot water to brush and rinse it off with. Afterwards, repeat this cycle once more, then let the rocks dry. This should be more than enough to get the rocks ready for your aquarium.


The bottom line, as you can see from your reviews, is that you can use many different rock types for your Cichlid tank we just covered what we feel are the best options (this one is our top pick). Tumbled bricks, river stones, real sea rocks, and ceramic ones too, they all work just fine. The most important thing to remember is that real sea rocks are great for coral growth, Cichlids like caves, and the rocks you get need to be treated so that they don’t leach chemicals into the water.
