Rotala indica is an excellent aquarium plant that adapts to most typical water conditions. It prefers good water quality with pH of 6.0-7.5, hardness of 3-8 dGH and temperature should be between 72 and 82° F. It is a relatively undemanding aquarium plant and in conditions of high light and nutrients with CO2 supplementation, it grows quickly and spreads across the surface of the water. For optimum growth lighting should be 3 to 5 watts per gallon provided by full spectrum (5000-7000K) bulbs. It can be planted directly on the bottom substrate of the aquarium. The substrate should be plain sand or small granulated gravel. It needs to be pruned regularly to keep their shape attractive. Without pruning, the plant takes a bushy appearance which makes a suitable place for fry or brood fish. The tank should have lean nitrate levels (~5 mg/l), high phosphate levels (~1.5-2 mg/l), and heavy, regular dosing of iron and trace elements which produce intense coloration and vigorous growth.
Rotala indica is a classic aquarium plant among the beginners and the experienced hobbyists due to its ease of cultivation and beautiful growth pattern.

Rotala indica can easily propagate in aquarium condition with proper care. Propagation can be done by taking a cutting off of the main plant. For perfect propagation, aqua soil powder is the ideal substrate which allows the roots to grow more quickly and easily within the substrate. During propagation, iron-rich fertilizers, trace elements and regular CO2 additions should be done. After cutting the top half of a strong stem, carefully place the cuttings into the substrate ensuring that the stem does not get crushed. Roots appear in a short time at the first node which aid in keeping the plant in place. Over time, it develops leafy and bushy plants. It occasionally can do sexual reproduction through seeds production and form new plants.
