Scopas Tang (Zebrasoma scopas)

Description:
The Scopas Tang, also known as the Brown Surgeonfish, is a member of the Zebrasoma genus, which includes several other tang species. This fish is easily recognized by its olive-brown to dark brown body, often with a hint of yellow on the fins and tail. Its body shape is typical of tangs, with a slightly flattened, oval profile, and it features sharp spines (also called "scalpels") on either side of the tail. These spines can be used for self-defense, making the Scopas Tang a bit more cautious around potential threats.
One distinctive feature of the Scopas Tang is its relatively modest coloration compared to other tangs, though its body can develop a more vivid yellow hue on the tail and fins as it matures. This fish can grow up to 8 inches (20 cm) in length, so it needs plenty of space in a tank.
Care:
Tank Size: As a larger tang species, the Scopas Tang requires a minimum tank size of 75 gallons to thrive. They are active swimmers and will appreciate a spacious tank that allows them to move freely. For optimal health and behavior, tanks of 100 gallons or more are recommended for adults.
Water Conditions: The Scopas Tang is a hardy fish that can adapt to a range of water conditions, but stability is key. Proper water parameters are essential for their long-term health:
Temperature: 74-80°F (23-27°C)
Salinity: 1.023-1.025 specific gravity
pH: 8.1-8.4
Ammonia, Nitrite: 0 ppm
Nitrate: Less than 10 ppm
Consistent water quality is vital, and good filtration is important to maintain stable conditions.
Diet: The Scopas Tang is primarily herbivorous, meaning it feeds mostly on algae. A vegetable-based diet is essential for their health, and they will graze on natural algae found on live rock. Supplementing their diet with marine algae sheets (nori), spirulina, and vegetable-based pellets or flakes is also highly beneficial. Occasionally, offering fresh vegetables such as spinach, lettuce, and zucchini can help meet their nutritional needs.
Being algae grazers, they are also known for helping to control algae growth in the tank, making them an excellent addition to a reef tank.
Tank Setup: Scopas Tangs prefer a reef environment with plenty of live rock for grazing and hiding. They also appreciate a sandy substrate, which provides them with a place to rest and forage for food. They are active swimmers, so good water flow is important to mimic their natural reef environment.
Having hiding spots and territorial areas is also important, as Scopas Tangs can be somewhat territorial, especially in smaller tanks.
Social Behavior: Scopas Tangs are generally peaceful but can be territorial, especially towards other tangs or similarly shaped fish. It's best to keep them with peaceful tankmates in a large aquarium, as they may become aggressive if crowded or if there are other tangs in the same tank.
They are typically peaceful toward other species but should not be housed with overly aggressive or overly shy fish. Avoid keeping multiple tangs unless the tank is large enough to accommodate them and provide enough hiding spaces.
Companions: Scopas Tangs do well with a variety of peaceful fish, including:
Clownfish
Wrasses
Gobies
Anthias
Other peaceful reef species
They should be kept away from aggressive fish or other tangs unless there is ample space for each fish to establish its territory.
Maintenance: Regular water changes (10-20% every two weeks) and a high-quality filtration system are essential for keeping the water quality in check. The Scopas Tang is sensitive to poor water conditions, so it’s important to maintain consistent water parameters.
Additional Considerations:
Growth and Space: Scopas Tangs can grow up to 8 inches (20 cm) in length, and their active swimming nature requires ample space. Crowded tanks can stress them out and lead to aggressive behavior or health problems. Therefore, a large tank (75 gallons or more) with sufficient rockwork and swimming space is crucial.
Health and Care: Like other tang species, the Scopas Tang is susceptible to marine ich (Cryptocaryon irritans) and other external parasites. Ensuring your tank has good water quality and a stable environment can help reduce the risk of infections. A quarantine tank is recommended for new arrivals to prevent the spread of diseases.
Temperament: The Scopas Tang is relatively shy compared to some other tang species. While not overly aggressive, it can become territorial in a small or overcrowded tank. Keeping them with compatible tankmates in a spacious environment will encourage a calmer, more peaceful demeanor.
