General Description
The Indian toothcup (Rotala indica) is a species that has caused confusion in aquaristics due to misidentifications with other plants, notably Rotala rotundifolia. True R. indica is distinct, with obovate-spatulate leaves that exhibit a cartilaginous margin and upright growth. This slow-growing plant features dense foliage, reddish shoot tips, and inconspicuous flowers on short lateral shoots.
Aquarium Suitability
Considered suitable for aquariums, Rotala indica requires high light intensity and nutrient supply. It is best planted in larger groups of varying stem lengths in the middleground of the tank. The species is categorized as medium difficulty in terms of care and maintenance according to aquarists.
Demands and Hardiness
See table for specific details on water conditions. Aquarium setup for R. indica should provide 10-40mg/l of CO2, high light levels, and nutrient levels within the specified ranges. It is essential to maintain a temperature between 22-28°C with a tolerance range of 18-30°C for optimal growth.
Aquascaping & Usage
This plant is suitable for midground and foreground placement in aquariums, particularly in nano tanks and Dutch-style aquascapes. Its almost pillar-like upright shoots add vertical interest to aquascape layouts, contributing to a visually enticing aquatic environment.
Propagation
Propagation of Rotala indica primarily occurs through cuttings. Regular pruning aids in promoting bushier growth and maintaining the desired shape within the aquarium.
Habitat and Distribution
Natively widespread in warmer regions of Asia and a common weed in rice paddies, R. indica has also been introduced to other continents where rice cultivation is prevalent, such as Northern Italy. The plant thrives in aquatic habitats, showcasing adaptability to various environmental conditions within its natural range.
