Tang- Gem
The Gem Tang (Zebrasoma gemmatum), also known as the Spotted Tang or Gemmatum Tang, is a rare and highly sought-after saltwater fish known for its striking appearance and distinct pattern of white spots on a deep black or dark blue body. It requires specific care to thrive in a home aquarium. Here are the care requirements for a Gem Tang:
1. Tank Size
Minimum Tank Size: 180 gallons (680 liters)
Gem Tangs are active swimmers and require a large tank with plenty of swimming space.
2. Water Parameters
Temperature: 74°F - 80°F (23°C - 27°C)
pH: 8.1 - 8.4
Salinity: 1.023 - 1.026 specific gravity
Alkalinity: 8 - 12 dKH
3. Aquarium Setup
Rockwork: Provide plenty of live rock to create hiding places, which also serve as grazing areas for algae, a natural part of their diet.
Swimming Space: Ensure there is ample open water for swimming.
Substrate: A fine sand substrate is recommended. It’s gentle on their fins and skin.
4. Diet
Diet Type: Herbivorous
Food: Their diet should primarily consist of marine algae and seaweed, such as nori. Supplement with high-quality herbivore pellets, and occasionally offer mysis shrimp or brine shrimp as a treat.
Feeding Frequency: Feed small amounts several times a day. Grazing on algae throughout the day is ideal for their health.
5. Temperament and Compatibility
Temperament: Generally peaceful but can be territorial, especially towards other tangs or similar-looking fish.
Tank Mates: Suitable for a community tank with other peaceful species. Caution is needed if keeping them with other tangs, particularly from the same genus (Zebrasoma), as aggression can occur.
Reef Compatibility: Reef-safe; they do not typically harm corals, invertebrates, or other reef inhabitants.
6. Behavior
Active Swimmer: Gem Tangs are constantly on the move, swimming throughout the tank, and grazing on algae. They appreciate a well-established tank with a mature algae population.
Territorial: They may establish and defend a territory, particularly from other herbivores or tangs.
7. Health
Disease Resistance: Gem Tangs are generally hardy but can be susceptible to common marine diseases like ich, especially when stressed. A stable and clean environment is essential.
Acclimation: A slow drip acclimation is recommended to help them adjust to their new environment and minimize stress.
8. Special Considerations
High Cost: Gem Tangs are one of the more expensive marine fish due to their rarity and beauty, so they are often kept by experienced aquarists.
Quarantine: It is advisable to quarantine a Gem Tang before introducing it to your main display tank to ensure it is free of disease and to allow it to acclimate in a less stressful environment.
Lighting: Moderate to high lighting is beneficial as it encourages the growth of algae, which is a primary food source for the Gem Tang.
9. Sexing and Reproduction
Sexing: There is no distinct visual difference between males and females.
Reproduction: Breeding in captivity is extremely rare and difficult. They are pelagic spawners, releasing eggs into the water column, making captive breeding a significant challenge.
With proper care, the Gem Tang can be a stunning and rewarding addition to a large, well-maintained saltwater aquarium.
