Microsorum Pteropus Thor's Hammer, also known as Java Fern Thor's Hammer, is a beautiful aquatic fern plant that works well in emersed settings and will also grow in any terrarium, vivarium, paludarium or enclosed container garden as long as sufficient humidity levels are met. Java Fern Thor's Hammer features bright green, leafy foliage with ends that resemble the shape of a hammer, earning its name. Java fern plants produce new growth from the rhizome and are an epiphytic genus, resulting in versatile placement. These fern plants will self-attach to porous surfaces such as aquascaping stones and aquarium driftwood. 

Java Fern Thors Hammer Easy Beginner Aquarium Terrarium Fern Plant

While it isn't required, Java Fern species will benefit from CO2 injection in a planted aquarium. Low to medium lighting and a regular fertilizing routine are beneficial to promote healthy growth. Java Fern is relatively slow growing, but with patience, has the potential to produce lush, leafy bushes of green in your setup when given the correct care and optimal conditions. When planting, Java Fern speices should not be buried in aquarium substrate as this can cause the aquatic plant to rot. Once settled in an aquarium tank, Java Fern Thor's Hammer can be propagated easily by separating the aquatic plant gently along the horizontal rhizome.
