The leaves of the banana plant (Musa sp. var. sapientum) have been successfully used in Asia for many years. There, they have long been used by successful ornamental fish breeders, in the same way as tropical almond leaves to prevent and treat diseases such as for example
- Fungal diseases
- Head and lateral line erosion in cichlids
- Damage to mucous membranes
- Bite injuries
- Fin rot
Breeders of Siamese fighting fish, in particular, swear by banana leaves and use these with even greater success than tropical almond leaves, as they improve the coloration of the fish and have very positive effects on the fishes' readiness to spawn (especially in Betta splendens fighting fish such as Half Moon, Plakat etc.).
Particularly with very sensitive species, such as for example Albis or Simplex, banana leaves provide an excellent alternative to tropical almond leaves, as the latter often cannot be used in such cases because of the water values.
