Nematanthes is a genus of flowering plants with small, succulent, and hard-surfaced leaves. The plant has a trailing, branching, and spreading habit. Generally epiphytic in nature and cultivated as a hanging-basket specimen. The flowers have fused petals giving it the appearance of a goldfish, hence the common name "goldfish plant".
Nemanthus are hardy succulents requiring little more than occasional water and plenty of sunlight.
