Plastic or Live
-
While live plants make a beautiful addition to any betta aquarium, plastic plants are easier to care for. Because bettas are generally kept solitary due to their aggressive nature, water oxygenation and decontamination aren't as important as they are with other aquariums, assuming that the aquarium is large enough. Either choice is suitable.
Local Laws
-
Choosing live plants to add to your tank is not difficult if you understand the mechanics of how water plants work. Most water plants are considered weeds and nuisance plants. This means that they will grow continuously and quickly take over the tank. Some of these plants are non native and are illegal to have in certain states. Check your local state regulations on legal water plants before buying. Also, never flush these plants down the toilet or throw them into lakes, rivers or rain drains.
Philodendrons
-
Philodendrons are popular natural plants that can be found easily. There are several different species of philodendron available.
Anacharis
-
Anacharis is another plant that is used in both indoor and outdoor aquariums. This plant has beautiful, needle like leaves that are safe for bettas to eat. They can be both free floating or rooted plants.
Java Ferns
-
Java ferns are another safe choice for betta tanks.
