Is Gravel Good For Fish Tanks?
Yes, for the most part, gravel is great for fish tanks, especially for freshwater tanks. Sure, sand works alright too, but sand is usually better for saltwater tanks (we have covered sand separately here).
The bottom line is that gravel does usually make for the best substrate option, as it tends to not alter the pH level in the water, it usually doesn’t have chemicals which leach into the water, and it tends to have the right shape and size consistency to support rooted aquarium plants. Many fish also prefer fine gravel as they can really root around in it.

Commonly Asked Gravel Questions
Let’s quickly go over some of the most commonly asked questions in terms of aquarium gravel, especially coloured aquarium gravel.
What Color Gravel Is Best For Betta Fish?
Ok, so this is really a matter of personal preference than anything else. You can get some dull and plain gravel if you want the colourful betta fish to be the center of attention.
If you really want to make the betta fish stand out above all else, you might actually want to go for some black aquarium gravel, as the black of the gravel will create a nice contrast against the bright and colorful betta fish.
To be quite honest, it’s not recommended that you get any brightly coloured aquarium gravel for a betta fish tank, as any colours will simply take the attention away from the betta fish.
Can I Use Normal Gravel For My Fish Tank?
Yes, normal gravel is just fine for most fish tanks. It’s not like coloured gravel adds any real or inherent benefits to a fish tank besides a neat look and overall aesthetics.
If you are not too worried about adding more colour to the fish tank, then yes, normal aquarium gravel will work just fine.
However, on a side note, if you are talking about normal gravel, as in the stuff people put on roads and walkways, then no, you cannot use this type of gravel for fish tanks. This kind of road gravel will contain various minerals and maybe even chemicals, which you absolutely do not want to be putting anywhere near your fish.
Most road gravel is also just way to larger and has rough edges that won’t mix well with delicate fish.
Is Sand Or Gravel Better For Aquariums?
If it is a saltwater tank we are talking about, then yes, you might want to go with sand. However, for most freshwater applications, you want to use gravel.
Gravel is just a lot easier to work with and to clean, it does not mess with the pH level of the water, and it does not cloud up the water as bad either.
Therefore, when it comes to freshwater fish tanks, you probably want to stick with gravel as opposed to sand.
The bottom line is that some nicely coloured, black, or even glow in the dark aquarium gravel can really make any fish tank come to life. Just be sure to pick the right colours that will contrast and mix nicely with the fish and plants you plan on having in your aquarium. We will leave it down to you to figure out which one is best for you.
