1. The Java Fern
The Java Fern is a great live plant for Betta fish, it’s super easy to grow and doesn’t require any special lighting, substrate, fertilizer or Co2. A full grown Java Fern can be up to 13″(inches) high and 6″(inches) wide.
The Java Fern will do best in a tank that is at least 10 gallons in size, which is an excellent size tank for your Betta along with a few tank mates.
Also, the temperature range and PH levels for the Java Fern are almost identical to the ideal water conditions for Betta fish.
There are four main varieties of Java Fern, they are;
- Needle leaf
- Lance leaf
Because they are so easy to care for, Java Fern can be placed in most tanks without any special lighting requirements.
However, you can have too much light. If the leaves become brown or almost transparent, your lighting levels may be too high.
Also, since they don’t have roots, they acquire nutrients from the water, so you may need to add some fertilizer after your water changes. Try not to use fertilizer tabs since they don’t have roots.
Java fern can be planted almost anywhere. They can be placed on decor, driftwood, rock, and substrate. However, be sure not to bury them in the substrate as they pull most nutrients directly from the water.
To attach Java Fern, use a color-matched thread, zip tie, or even fish line for best results. Some people use rubber bands which are very visible and look horrible.
To maintain Java Fern is pretty easy, just keep up on weekly checks and trim any dead or discoloured leaves. Because Java Fern are so hardy it’s pretty difficult to kill them.
