Cryptocoryne
Several dozen species of this genus are used in aquariums, which sometimes gives
rise to confusion. Some are genuinely aquatic, others amphibious. The quality of
water required varies according to the species: soft to moderately hard, slightly
acid to alkaline; the soil must always be quite rich. Sexual reproduction with flowers
is rare; vegetative multiplication occurs by means of runners or the division of
the clump.
Cryptocoryne balansae
Balansa's cryptocoryne prefers intense light and a temperature over 25°C. It
should be kept as a single specimen, to highlight it. Size: 40 cm.
Cryptocoryne beckettii
Beckett's cryptocoryne, paludal in the wild, is very resistant and can live totally
submerged. Size: 40 cm.
Cryptocoryne ciliata
The ciliated cryptocoryne is one of the species in this genus that tolerates
hard water, and it requires fairly rich soil. It is amphibious in its natural environment.
Size: 40 cm.
Cryptocoryne cordata
The Siamese cryptocoryne exists in several varieties, which differ from each
other in the shape of their leaves. It adjusts well to hard water. Size: 15-20 cm.
Cryptocoryne crispatula
A large hardy species, the undulated cryptocoryne is reserved for big aquariums,
where it deserves to be shown off. It dislikes water that is too hard. Size: 50-70
cm.
