What Plants Are Safe for Betta Fish Aquariums?

Read on to discover the safest plants to use in your betta's aquarium...

To make them appear as natural as possible, plants are often added to betta fish aquariums. When considering adding plants to your betta aquarium, it is important to know the types that are safe for your fish. Plants that are safe to use in a betta fish aquariums include those that are soft-edged and non-toxic.

Soft Edges

Betta fish have very fragile fins that can be harmed quite easily if scratched. You should make sure any plants you put into your betta's aquarium do not have any rough edges. If you have purchased artificial plants to add to the aquarium, test the seams by running them across some pantyhose. If the plant tears the pantyhose, you know the edges of the plant are too sharp and could hurt your fish. Take the artificial plant back to the store!

Non Toxic

Your betta fish may attempt to eat the plants in the aquarium, so be sure the plants are non toxic. Most artificial plants sold from pet stores have been created with live animals in mind, and so should be safe to use in your betta's home.

If you are using live plants in your betta's aquarium, you should be sure to purchase them from a pet shop, and make sure to discuss your betta's well being with a pet store associate. The associate will be likely to help you pick out the best plants for your betta's aquarium.

Some plants that are generally safe to use in a betta aquarium include Chinese evergreen, peace water lilies and photos plants. Most pet stores that carry aquarium accessories should also sell these aquarium-safe plants.
