For best care, the Yellow Tang should be housed in an established, well-filtered aquarium of at least 100 gallons.
To best recreate a natural reef environment for your Yellow Tang, aquascape generously with live rock but be sure to arrange your reef aquarium landscape so there are open areas with ample room to swim. Consider enhancing water movement for your Yellow Tang by employing powerheads or wavemakers.
Like other Tangs, this member of the Acanthuridae family demonstrates territorial aggression towards its own species, or Tangs in general. Therefore, it is best to keep just one Yellow Tang per aquarium, unless multiple Yellow Tangs are introduced simultaneously into a very large system.
Although the Yellow Tang will eat meaty foods it is important the Yellow Tang is offered plenty of marine-based seaweed and algae. This will strengthen its immune system, reduce aggression and improve overall health. Offer dried seaweed, or Nori by way of veggie clip along with Spirulina or algae pellets.
