Key Takeaways:

Before we dive into the specifics of caring for Dottybacks, let’s take a quick look at the key takeaways:

  • Dottybacks are colorful and playful fish that require a well-maintained saltwater aquarium.
  • Proper tank setup, water conditions, and feeding habits are crucial for their overall well-being.
  • It is best to keep Dottybacks with other non-aggressive fish, as they can be territorial.

Now, let’s move on to the detailed guide on how to care for these captivating creatures.

Tank Setup

Setting up the right environment for your Dottybacks is crucial to their health and well-being. Here are some essential factors to consider when preparing their tank:

  1. Tank Size: Dottybacks are small but active fish, so it is recommended to have at least a 30-gallon tank for a pair or small group of Dottybacks. The larger the tank, the better it is for the overall stability of the water parameters.

  2. Water Parameters: Maintaining stable water conditions is crucial for the health of your Dottybacks. Keep the water temperature between 75 to 80 degrees Fahrenheit (24 to 27 degrees Celsius) and the salinity between 1.020 and 1.025 specific gravity. Regularly test the water’s pH, ammonia, nitrite, and nitrate levels to ensure they are within acceptable ranges.

  3. Filtration: A strong and reliable filtration system is essential to keep the water clean and free from pollutants. Consider using a combination of mechanical, chemical, and biological filtration methods to maintain optimal water quality.

  4. Decorations: Dottybacks love to explore and hide, so provide plenty of hiding spaces and caves in the tank. Use live rocks or artificial decorations to create a natural-looking environment.


Dottybacks are carnivores by nature, so providing a well-balanced diet is essential for their health and vitality. Here are some feeding tips to keep in mind:

  • Offer a variety of high-quality foods, including frozen or live meaty foods such as brine shrimp, mysis shrimp, and small pieces of fish or shrimp.
  • Supplement their diet with a high-quality pellet or flake food designed for carnivorous fish.
  • Feed them two to three times a day, giving them only what they can consume within a few minutes. Overfeeding can lead to poor water quality and health issues.


When choosing tankmates for your Dottybacks, it’s important to consider their territorial nature. Here are some compatible options:

  • Non-aggressive fish, such as gobies, blennies, and clownfish, make great tankmates for Dottybacks.
  • Avoid keeping them with larger, aggressive fish or other fish with similar body shapes, as they may become aggressive towards each other.
  • Always observe their behavior and be prepared to rearrange the tank if any aggression occurs.

Common Health Issues

Like any other fish, Dottybacks are susceptible to certain health issues. Here are a few common problems to watch out for:

  • Ich (white spot disease): Look for small white spots on the fish’s body or fins. Treat with a high-quality ich medication following the manufacturer’s instructions.
  • Marine velvet: Watch for signs of rapid breathing, scratching against objects, or a velvety appearance on the fish’s skin. Quarantine and treat affected fish immediately.
  • Fin rot: Keep an eye out for shredded or discolored fins. Improve water quality and consider adding a bacterial treatment to the tank.

Remember, regular observation and proper maintenance of the tank will go a long way in preventing health issues.


Caring for Dottybacks can be an enjoyable and rewarding experience. By providing them with the right tank setup, proper feeding habits, and compatible tankmates, you can ensure that your Dottybacks thrive in their saltwater aquarium. Remember to maintain regular water testing and be vigilant for any signs of illness. With a little care and attention, your Dottybacks will bring color and joy to your aquatic haven. Happy fishkeeping!
