Its fine foliage is much appreciated by certain fish which lay their eggs on
it or, depending on the species, munch on it. These amphibian plants can live submerged,
and when they reach the surface of water they spread out on top of it. At this point
cuttings should be taken and transplanted. Good lighting is essential. A lack of
iron causes their leaves to turn yellow.
The aquatic ambulia grows well in soft or slightly hard and acid water, providing
it has an adequate supply of mineral salts. Small shoots from its base are perfect
for cuttings, although removing the top is equally effective. This ambulia must
be planted in clumps, with the stems slightly separated to take advantage of the
light. Size: 30 cm.
The heterophyllous ambulia is less tufted than the above, but its tips must nevertheless
be removed regularly. Size: 30 cm.
