About this fish
About this fish
Domino Damsel (Dascyllus trimaculatus) is a saltwater damselfish for the home aquarium, known for being hardy, colorful, and active. In day-to-day use, it makes a lively “rock-dweller” that tends to claim a space in the tank, so it’s a practical choice when you want visible movement and confident behavior in an established reef or reef-style setup.
Features:
- Active and colorful, adding noticeable movement to the aquarium.
- Typically reef safe with corals when kept in a suitable tank environment.
- Often becomes territorial as it matures, especially around its chosen rock area.
- Tends to do best when aquascaped with plenty of rock for sight breaks and territory options.
- Usually acclimates well when introduced slowly and given time to settle.
- Diet is straightforward: it accepts small frozen foods and quality flakes or pellets.
- A calm, quiet settling spot after arrival can help reduce initial stress.
