Crinum thaianum — commonly known as the Onion Plant — produces very long, strap-like, wavy leaves that make it one of the most distinctive background plants for larger aquariums. The leaves can grow well beyond 1m in good conditions, making it ideal for concealing equipment such as heaters and filters behind lush trailing foliage.
A useful characteristic: fish that typically graze on aquarium plants tend to leave Crinum thaianum entirely alone — apparently deterred by its flavour. This makes it a reliable choice for tanks with herbivorous fish where other plants struggle to survive. Care requirements are simple: low light, no CO2, and only the lower third of the bulb buried in the substrate. Bury it more deeply and the bulb will rot.
Note: the specimens we receive rarely have as many leaves as shown in the product image — the picture shows a mature specimen at its best. Individual plants vary naturally.

The bulb resembles a large onion. It's planted in the substrate, from which the long strap-like leaves emerge.
No — fish almost universally avoid Crinum thaianum, apparently because of its taste. Popular in tanks with herbivorous fish for this very reason.
Only the lower third of the bulb should be in the substrate — no more. Burying it deeper causes rot.
Well over 1m in good conditions — primarily a plant for larger aquariums where leaf length won't be a problem.
No — it's suitable for low-tech setups without CO2 supplementation.
