Obsidian Tang \u2013 Acanthurus gahhm<\/em><\/h3>\n

Overview:<\/strong>
The Obsidian Tang is a striking marine herbivore, known for its deep black to dark gray body with subtle blue highlights and a contrasting vibrant yellow tail. Its bold coloration and active swimming make it a standout in large reef aquariums.<\/p>\n

Origin:<\/strong>
Native to the Indo-Pacific<\/strong>, primarily found along coral reefs and lagoons in Red Sea, East Africa, and the western Indian Ocean<\/strong>.<\/p>\n

Feeding:<\/strong>
Primarily herbivorous \u2013 thrives on marine algae, seaweed, and spirulina-based foods<\/strong>, supplemented occasionally with meaty foods like mysis shrimp for balanced nutrition. Regular feeding helps maintain coloration and digestive health.<\/p>\n

Tank Mates:<\/strong>
Best kept with peaceful to semi-aggressive tank mates<\/strong>. Avoid housing with overly aggressive tangs to minimize territorial disputes.<\/p>\n
