110 Convict Tang "Manini" - This fish is the most common surgeonfish in Hawai‘i and a tang is a type of surgeonfish because it has a sharp spike at the base of the tail that will give a diver or predator a deep cut if they get too close. Manini is a super important fish to keep our coral reefs healthy. The large schools of manini flow with the shallow water waves over the coral reef, grazing on algae, which gives room for the corals to grow. This gourd is pyro-etched, painted & completely sealed inside and out. Dimensions: 6.7 x 7" weight 8 oz.
