Appearance

Small green leaves in pairs along a bright green stem. At a glance it passes for a bacopa; the stems are thinner and the whole plant lighter.

Keeping

Easy: it grows in most conditions, needs no carbon dioxide, and asks only for decent light and a reasonable substrate. Growth is fast, so trimming is regular. It also grows above the waterline in a marsh setup.

Placement

The middle or back of the tank, in a group; small enough for a nano tank when trimmed.

Propagation

By cuttings, which root in the substrate without trouble.

Water conditions match

The water suits 983 of 1249 species in the catalogue — these are the ones people look up most often.

Matching water does not mean the fish will leave the plant alone.

The same plant with a different look: light, water and care are shared with the species.
