ID these plants. Land ferns ?

[peterkoh]

Bought these ferns from Thatfishsop at Yishun.

Looks very much like land fern. They came in stalks so just stick them into the substrate. Been there for more than 2 months and don't seem to be growing. Are these land ferns disguised at aquaplants ? If not, how to grow them ? Also contain other pictures of my tank (2 ft 36 watt). Thks.

Yes, they are land ferns: Selaginella sp. Won't survive for long underwater. But hard to grow as well as they need high humidity. Best for covered terrariums.

Thks. Both types or 1 of the 2 types shown ? cos i plan to remove them if they are land ferns.

The 2nd one is definitely a Selaginella. The first looks more like a Trichomanes, which is also non-aquatic. Both grow naturally in moist habitats, e.g. near streans and waterfalls.
