Microsorium
This genus includes ferns with a clear predilection for humid environments. Only
one species is of any great interest to aquarists.
Microsorium pteropus
The Javan fern grows slowly, under moderate to intense light, but it is very
hardy. Like all ferns, it can reproduce sexually with spores, but vegetative reproduction
is much more common in an aquarium. The rhizome can be cut off when young fronds
appear, and can attach itself to a support with the help of small roots. This process
can be encouraged by wedging the rhizome between stones - taking care not to squash
it - or tying it down with a nylon line. Size: 15-20 cm.
