Your Guide to Buying and Adding a Blue Damsel to Your Tank
The Blue Damsel, often associated with vibrant blue coloration and energetic demeanour, is a common choice for many aquarists venturing into the marine aquarium hobby. Its hardiness and relatively simple care requirements make it an appealing option, especially for newcomers.
Choosing the Right Blue Damsel
When selecting a Blue Damsel:
- Ensure it showcases bright, vivid blue scales with active and alert behaviour.
- Avoid those with any signs of distress, such as torn fins, faded colours, or erratic swimming patterns.
Physical Appearance
Characteristics of the Blue Damsel include:
- Compact, streamlined body growing up to 2-3 inches in length.
- Luminous blue coloration covering the entirety of its body.
- Sleek, agile swimming capabilities.
Compatibility with Other Fish
In terms of tankmate selections:
- While Blue Damsels are often robust and resilient, they can exhibit territorial behaviour, especially as they mature.
- It's advisable to house them with fish that aren't too timid or prone to being bullied.
- Introducing them last to the tank can mitigate some territorial disputes.
Reef Safe
For reef enthusiasts:
- Blue Damsels are generally considered reef safe.
- They typically don't disturb corals but can sometimes pester small invertebrates.
Suitable Tank Size
Keeping their size and activity in mind:
- A minimum tank size of 100 litres is suggested. Bigger tanks can reduce aggression and territorial disputes.
Water Conditions
To keep them thriving:
- Temperature:22-27°C.
- pH levels: 8.1-8.4.
- Specific gravity: 1.020-1.025.
Preparing Your Tank
Setting up a suitable environment:
- Incorporate various rock formations and caves for them to claim and retreat to.
- Ensure strong water movement and filtration to mimic their natural habitat.
Monitoring Behaviour
Regular observations are key:
- Blue Damsels are often bold and assertive. Monitor for excessive aggression.
- Check regularly for any signs of disease or health issues.
Feeding Schedule
For a healthy diet:
- They are omnivorous and thrive on a variety of foods.
- Offer marine flake or pellet food, complemented with occasional live or frozen foods such as mysis shrimp or brine shrimp.
- Feed once or twice daily.
The Blue Damsel, while being a sturdy and hardy marine fish, requires proper care and attention to its behaviour, especially concerning its relations with other tank inhabitants. With the right environment and diet, they can be a colourful and lively addition to any marine aquarium.
