Eleocharis parvula, eleocharis vivipara, microsorum pteropus 'philippine' (the little version of java fern) and some mosses maybe some cryptocoryne undulata near the wood and other carpeting plants like lilaeopsis brasilensis or echinodorus tenellus and some bolbitis heudelotii in the back, unfortunately the image is in poor quality to identify all proper but this is my guess.
Cheers,
