Environment
Plan for an aquarium of at least 100 liters and sufficiently tall, as its leaves can reach 40 to 50 cm. It appreciates rather neutral water (pH 6.0 to 7.5) between 22 and 28 °C, in stable parameters. Give it space, as an adult rosette occupies considerable volume.
Feeding
Nutrient-demanding plant with primarily root nutrition: a rich nutrient substrate or fertilizer tablets placed under the roots are essential for its vigor. Medium lighting is sufficient, and CO2 injection is not essential but promotes denser growth. Supplement if needed with an iron-rich fertilizer to prevent yellowing of leaves.
Tips & tankmates
Regularly remove old damaged or yellowed leaves at the base to stimulate renewal. It propagates via flower stalks bearing plantlets that can be detached and replanted. Avoid moving it too often, as its deep root system dislikes being disturbed.
