hi! thank you all!
The substrate is seachem flourite. i' ve been using it for a couple years now, so i want to believe it's pretty much "charged" now..
Some of the plants are:
alternanthera reineckii mini,
hydrocotyle tripartita,
hygrophila pinnatifida,
bolbitis heudelotii,
fissidens fontanus,
ammania bonsai,
staurogyne repens,
rotala rotundifolia,
lobelia cardinalis mini and
Proserpinaca palustris.
there are also some crypts, buchepalandras and ferns. Any plants suggestions for the background??
