Plants will grow with ordinary bulbs as they tend to have both some blue and red emissions. The problem is that they also have wavelengths between 500 and 600nm, which algae likes. Green algae and green plants use the same pigments for photosynthesis (chlorophyll a/b & carotenoids). So, light that helps one helps the other. The algae that are different are the blue-green algae (cyanobacteria), which contain Phycocyanin and absorb light heavily in the low 600nm (orange-red), which is unfortunately present in most standard fluorescents. In the planted aquarium artificial light should ideally peak (or be stronger) in the red area of the spectrum. The tanks’ appearance can be compensated (balanced) with blue light and some green light for brightness to the human eye. Strong blue light will cause plant growth to be more compact and bushy and will also tend to promote algae growth. So remember to balance 2/3 red to 1/3 blue light emissions.
Red Aquarium Plants – Aquarium Co-Op
I have yet to determine the maximum size. Mine was larger than many of the maximums stated by others in less than a month, and it continues to grow. These incredibly beautiful plants are deemed pond plants by many because of their extreme growth rate. This growth rate is considered a problem in an aquarium, but the difficulty is easy to overcome.
Foxtail RED, Myriophyllum heterophyllum, live aquarium plant
Red tiger lotuses are easy to grow in aquariums. They develop large root systems and do well with fertilizer in their substrate. Iron-rich clay aggregate is an ideal planting medium.

Alternanthera reineckii roseafolia, colorful plant $3.19 Alternanthera reineckii offers a nice contrast to the mostly green plants in an aquarium. Although most red aquarium plants are somewhat difficult to grow in an aquarium, Alternanthera reineckii is relatively easy. With adequate light and fertilizer Alternanthera reineckii grows vigorously and with good color.First, the aquarist can attempt to avoid introducing red algae into anuncontaminated aquarium. This is most important if red algae is seen in thelocal area, say, in the local aquarium shops. Contamination fromtransferred plants is likely, even if the algae isn't clearly visible. Inthese situations, a suggested approach is to 'disinfect' the plants to killthe red algae. It may also be helpful to avoid using any water from anaquarium shop (e.g. acclimate new fishes in a bucket) and quarantee newfish for a few days until they clear their digestive system.Simon also wonders if very high light levels and iron levels may be the keyto prevention. His question appears to be rhetorical because both of theseparameters are important indicators of plant and algae growing conditions inthe aquarium. Sufficient light is need for good plant growth and generallyspeaking the rate will increase with higher intensity. Actively growingplants will also soak up nutrients from the water column helping to starvealgae. While rooted plants can derive nutrients from the substrate, algaebasically get their food from the water. If nutrients concentrations arereduced in the water column, the algae will suffer.Cryptocoryne wendtii “Red” is a very adaptable aquarium plant which originates from Sri Lanka, with red-brownish leaves, that can be used in any area of the aquarium, emerged and submerged, if lighting and fertilization permits (preferably an iron-rich fertilizer). This wonderful plant responds to light, so its growth depends heavily on light intensity. In aquariums with moderate light, it grows considerably taller, often reaching heights of 30-45 cm.
