Ceratophyllum submersum is easy to keep and can be planted or left floating. Low light is enough, but Ceratophyllum demersum will grow faster with increased light and is good if you need to remove excess nutrients from the water. Ceratophyllum submersum has sfoter and more fragile stems and leaves than Ceratophyllum demersum.

The original Hygrophila corymbosa. An undemanding plant for large
aquariums, which thrives in almost any conditions. If it is not pruned it easily
grows above the water surface, where it forms dark-green leaves and beautiful
blue flowers. This makes it particularly suitable for open aquariums. It is most
beautiful in groups, but the shoots must not be planted too close, because this
will prevent light reaching the lower leaves.

Few aquatic plant species are as tough or as accommodating as this one. Light intensity seems to be rather unimportant, though lower light values will result in proportionately slower and more diminutive growth. Fertilization, as well, seems to be of limited significance in the maintenance of this species. Its stems will tolerate a variety of hardness values without showing a noteworthy decline in their exceptionally quick growth. CO2 supplementation is definitely not a necessity for this species, and it can be grown in non-CO2 aquaria without problems. In this light, it is a recommendable beginner�s plant.

Since H. polysperma develops a multitude of lateral shoots at its leaf nodes, propagation is a simple matter of removing these and replanting them. An aquarist might also �top� the stems by removing and discarding all of the shoot apexes that rise above a given level in the aquarium; new growth will shortly materialize. The growth of this species is often so rapid that a trim of some sort is required within two or three weeks of the last pruning.

Hemianthus micranthemoides is an easy to grow stem plant that will grow well in a wide range of water conditions, tank parameters, and fertilization schemes.  At minimum, moderate lighting should be provided to allow the leaves to grow into a rich bright green.

Cryptocoryne wendtii ‘brown’ is an undemanding plant that can be sustained in wide ranges of lighting environments, water acidity, and nutrient fertilization. When first introduced into a new environment, like many other cryptocorynes species, Cryptocoryne wendtii ‘brown’ will melt/shed its leaves. This is a normal process, and new leaves will sprout from the root bundle.

This plant will reach a maximum height of 10-12 inches (12-15 cm) and span 4-12 inches (10-15 cm).  The new emerging leaves will often develop from a bright green into a rich red-brown coloration. It has a slow growth rate under both high (slightly faster) and low light conditions.  It is a heavy root feeder which will reach optimal growth if provided ample substrate fertilization.
