Sulphur Damselfish Trio (3 Damsels)
The Sulfur Damsel is a vibrant and hardy species that is native to reefs from Eastern Asia to the Red Sea.
These fish should be added to well-established aquariums with ample space to swim, featuring plenty of rockwork, caves, and crevices. Groups of juveniles can be introduced to larger aquariums, but they may become more aggressive and territorial as they mature, especially toward other fish of the same genus or similar size.
Feed a balanced diet including meaty and algae-based foods such as Spirulina.

The trio arrived quickly and are active in the tank. They seem to enjoy the algae-based food and have settled into the rockwork well. I’ve noticed they’re more active during the day and hide in crevices when the lights dim. Good coloration and hardy behavior so far.

They were easy to set up and have adapted well to the tank. I’ve been feeding them Spirulina and some meaty flakes. They don’t seem aggressive with other fish yet, though I’ll monitor their behavior as they grow.

The fish are colorful and active. I’m cautious about adding more fish due to their territorial tendencies. They seem to prefer areas with caves and rocks. Feeding them a mix of meaty and algae-based foods keeps them healthy.
