Thank you very much for the info!That is some kind of Peperomia. Most Peperomia live in the tops of trees or on rocks. They are not marginal aquatics.
For best results in a riparium use true marginal aquatics. Marginal aquatics are adapted to grow with thei roots in the water and they make the best representation of the riparian habitat. There are lots of good choices. Here is a quick list with some of the best...
- Ruellia Bluebell
- Cyperus Dwarf Umbrella Sedge
- Avicennia Black Mangrove and other mangrove trees
- Spathiphyllum Peace Lily
- Asclepias curassavica Mexican Milkweed
- emersed Bacopa monierri, various Hygrophila, Limnophila aromatica and the emersed forms of many other aquatic stems
- Echinodorus cordifolius and E. cordifolius 'Tropica Marble Queen'
- Colocasia fallax Dwarf Taro
- Pogonatherum Baby Panda Bamboo
- various Pandanus sp.
- Alternanthera Joseph's Coat - trellis raft
- Pilea Aluminum Plant - trellis raft
- Oplismenus Basket Grass - trellis raft
- various emersed Cryptocoryne - for high-humidity riparium
- emersed Anubias - for high-humidity riparium on trellis raft
- Bucepahaldra - for high-humidity riparium
- emersed Microsorum Java Fern- for high-humidity riparium on trellis raft
