Longan Leaves (20 Pack)

Longan Leaves are a lesser-known but highly respected aquarium botanical in parts of Asia, where they have long been used by fishkeepers and turtle keepers as a natural conditioning aid. Often described as a cure-all leaf, Longan leaves are traditionally used to help fish recover from transport stress, balance aquarium pH, and reduce the risk of fungal or parasitic issues.

At Castle Dawn Aquatics, we regularly use Longan Leaves in quarantine tanks and holding ponds, particularly for fish that have undergone long-distance transport. In our experience, fish conditioned with Longan leaves recover faster and appear less prone to stress-related illness.

If you are searching for a botanical with properties similar to Indian Almond Leaves, but without rapid pH drops or overly dark water, Longan Leaves are an excellent alternative.

Tannins Released: High

All our leaves are organically sourced and free from harmful pesticides.

Our leaves are cosmetically varied, as nature intended. Colour, shape, size, and appearance will vary naturally
