Overview
What to know before you buy.
A bright yellow damsel, hardy and reef safe but increasingly territorial as it matures. Add it late and give it rockwork to claim.
Care guide
Keeping Lemon Damselfish healthy in a South African setup.
Tank setup
A minimum 100L aquarium suits Lemon Damselfish. Use robust décor and sight breaks so each fish can hold its own space.
Water parameters
Keep pH 8.1–8.4 and 24–27°C. Stable parameters matter more than chasing perfect numbers; acclimate new arrivals slowly.
Feeding
Omnivore — frozen and prepared foods. Feed small amounts it clears in a couple of minutes, and vary the diet.
Behaviour
Territorial, especially with age. Watch it at feeding time and at lights-out to see its real temperament in your tank.
Tankmates
Choose robust tankmates of similar size, and nothing small enough to be eaten. Add Lemon Damselfish last so territories reset.
Breeding
Breeding success with Lemon Damselfish depends on the line and water chemistry; ask your shop about proven pairs.
