Your Guide to Buying and Adding a Diadema Dottyback to Your Tank

The Diadema Dottyback, also known as the Royal Dottyback, is an attractive and vividly coloured fish that can be a vibrant addition to many saltwater aquariums. However, potential owners should be aware of its temperament and the considerations needed for its care.

Choosing the Right Diadema Dottyback

When purchasing a Diadema Dottyback:

  • Opt for aquacultured specimens when available. These are generally healthier and have a lesser environmental impact.
  • Ensure they exhibit vibrant colours and show active behaviours at the store.

Physical Appearance

Characteristics of the Diadema Dottyback include:

  • Striking coloration with a purple anterior and bright yellow posterior.
  • Compact body shape, growing to about 3 inches in length.
  • Agile movement with darting behaviour.

Compatibility with Other Fish

In terms of cohabitation:

  • Diadema Dottybacks can be aggressive, especially towards other similarly sized and shaped fish.
  • They might bully or dominate smaller, peaceful species.
  • It's best to introduce them to the tank last, to reduce territorial disputes.

Reef Safe

On the topic of coral compatibility:

  • Generally, they are considered reef safe and don't harm corals.
  • However, they may prey on small ornamental shrimp or other tiny invertebrates.

Suitable Tank Size

Given their size and territorial nature:

  • A tank of at least 100 litres is advised.
  • Ensure there are multiple hiding spots and caves to reduce territorial conflicts.

Water Conditions

To maintain the health of a Diadema Dottyback:

  • Temperature: 22-25.5°C.
  • pH levels: 8.1-8.4.
  • Specific gravity: 1.020-1.025.

Preparing Your Tank

Before introducing this vibrant species:

  • Install plenty of rockwork to create nooks, crannies, and caves.
  • Ensure the tank is well-established, with stable water parameters.

Monitoring Behaviour

Observational insights:

  • Diadema Dottybacks are territorial and may stake out a particular area of the tank.
  • Monitor interactions with other fish to prevent excessive bullying or stress.
  • Their vibrant coloration can fade if they're stressed or unhealthy.

Feeding Schedule

When it comes to their diet:

  • They are carnivorous, favouring meaty foods.
  • Feed a variety of high-quality marine-based flake foods, brine shrimp, mysis shrimp, and other similar offerings.
  • Aim to feed them small amounts several times a day.

Adding a Diadema Dottyback to your tank can elevate its aesthetic appeal due to the fish's striking appearance. However, understanding and catering to its territorial nature will be key in maintaining a harmonious aquarium environment.
