Caring for Rhinecanthus verrucosus, commonly known as the Bursa triggerfish, in an aquarium requires attention to several key aspects to ensure their health and well-being:

1. Tank Setup:

  • Provide a spacious aquarium with a minimum of 100 gallons for a single Picasso triggerfish.
  • Ensure adequate hiding spots such as caves, PVC pipes, or live rock formations to mimic their natural habitat and offer security.
  • Use sand or fine gravel substrate to create a natural environment and allow them to exhibit their natural behaviors like sifting through the sand.

2. Water Parameters:

  • Maintain stable water parameters: Temperature: 75-82°F (24-28°C), pH: 8.1-8.4, Salinity: 1.020-1.025.
  • Ensure efficient filtration and regular water changes to keep ammonia, nitrite, and nitrate levels in check.
  • Picasso triggerfish are prone to producing a lot of waste, so a powerful protein skimmer is recommended to help maintain water quality.

3. Diet:

  • Offer a varied diet consisting of high-quality pellets, frozen or fresh seafood, and occasional live foods like shrimp or squid.
  • Provide a mix of meaty and plant-based foods to meet their nutritional needs.
  • Avoid overfeeding, as triggerfish can be prone to obesity and related health issues. Feed them 2-3 times a day, only what they can consume in a few minutes.

4. Tankmates:

  • Choose tankmates carefully, as Picasso triggerfish can be aggressive towards other fish, especially smaller or similarly shaped species.
  • Avoid keeping them with slow-moving or passive fish that may become targets of aggression.
  • Compatible tankmates include larger, robust fish with similar aggression levels, or fish that inhabit different areas of the tank.

5. Behavior and Aggression:

  • Monitor their behavior closely, especially during feeding times and when introducing new tankmates.
  • Picasso triggerfish can be territorial and may establish dominance within the aquarium. Provide plenty of space and hiding spots to minimize aggression.
  • If aggression becomes a problem, rearrange tank decorations to disrupt territories or consider removing the aggressor to a separate tank temporarily.

6. Tank Maintenance:

  • Perform regular water tests to monitor water quality and ensure parameters remain within acceptable ranges.
  • Clean the aquarium regularly, including gravel vacuuming, algae scraping, and filter maintenance.
  • Keep an eye out for signs of illness or distress, such as loss of appetite, abnormal behavior, or visible signs of disease, and address any issues promptly.

By providing a suitable environment, appropriate diet, and careful attention to their behavior and tankmates, you can help ensure the health and well-being of Picasso triggerfish in your aquarium.
