Plants by lighting level

BRIGHT TO VERY BRIGHT

These plants require a high-intensity light for a large proportion of daylight hours. In most cases, fluorescent tubes will not provide sufficient light to promote good growth. Use metal-halide or mercury vapor lamps.Red plants, such as this Myriophyllum tuberculatum, thrive in very bright light. Alternanthera reineckii, Ammannia gracilis, Bacopa monnieri, Blyxa echinosperma, Blyxa japonica, Cabomba aquatica, Cabomba piauhyensis, Cryptocoryne parva, Didiplis diandra, Echinodorus macrophyllus, Eichhornia azurea, Eichhornia crassipes, Eleocharis parvula, Eusteralis stellata, Fontinalis antipyretica, Glossostigma elatinoides, Heteranthera zosterifolia, Hydrocotyle sibthorpioides, Hydrocotyle verticillata, Hygrophila corymbosa ‘Crispa’,Hygrophila corymbosa ‘Strigosa’, Hygrophila difformis, Hygrophila guianensis, Hygrophila stricta Lilaeopsis novae-zelandiae.

BRIGHT

Metal-halide or mercury vapor lamps are still the ideal choice for these plants although in aquariums less than 18 in (45 cm) deep, two or three fluorescent tubes (with reflectors) may be sufficient. If the plants are densely grouped together, use metal-halide or mercury vapor lamps; if they are not and there is plenty of open space, then fluorescent tubes will be adequate.

MODERATE

These plants can be kept with two or three fluorescent tubes and are relatively hardy species. Although some wifi survive and grow under only one or two tubes (with reflectors), they will not grow at an optimum rate and may not show their full health. Most of the plants in this group will do better with brighter light, but they do not require it.

UNDEMANDING OR SHADED

The plants in this group are ideal for aquariums with just one or two fluorescent tubes. Some will live happily in a wide range of lighting conditions, others prefer to be in shaded areas or away from bright light.
