However, what you should remember when choosing gravel is to avoid sharp edges so that betta fish don't damage their fins. We often consider that the goal of the hobby of aquariums is the natural aspect. Aquarists want to simulate nature and bring it into their homes. Natural colors are usually the best option.
The shades of the brown color palette, neutral grays and off-white tones are splendid gravel colors to choose from. Other fish farmers don't like the light-colored substrate because fish feces and other waste seem so obvious. Gravel is the best option for betta tanks if you want to avoid maintenance. Sand is the next best option, but it can be compacted and needs to be raked for the aquarium to be healthy.
Marble is not a good option, since it traps a lot of betta debris and you have to move it to clean it properly. Check if your beta fish decides to stay at the top of the tank and doesn't even go down to explore close to the substrate. Instead, the best option will be to provide a manageable substrate that offers similar characteristics for your betta fish. Among them, aquarium gravel coated with pure water pebbles stands out as the best substrate for betta aquariums.
On the contrary, its color is just right so that the betta fish still stands out against the aquarium floor. The five products mentioned above represent a range of materials that you can use for your betta tank. Non-uniform grains also allow water to flow to the cover, a feature that works well if you use a filter to place under the gravel in your betta tank. This is often an aesthetic choice for the amateur rather than the best choice for betta fish per se.
However, overall, this is a solid ground option for your tank and will work especially well when you have a darker betta. Aquarium floors with a gravel or sand surface are the favorite substrates of betta breeders who have tanks planted. In addition, for a beta tank larger than 5 gallons (5 gallons is the smallest size for a betta), you may need two bags. It's not recommended to fill your tank with lots of plants if this is your first time having a beta fish, but once you get used to caring for a beta fish, it's something you can consider.
And the best part is that the stones are smooth, so I didn't have to worry about my betta being cut with them. If you want to create an attractive-looking tank floor, Pure Water offers vibrant colors that both you and your bettas will enjoy. Some betta fish farmers, including many beginners, consider that not covering up is the best option in their betta tanks. An important consideration when installing a betta fish tank is whether or not you will use live plants.
Remember that your betta fish is a very territorial fish and having a fish tank with a bare bottom can make it see its reflection all the time when the fish tank light is on.
