Overview
What to know before you buy.
A hovering dartfish in purple and gold that bolts into rockwork when startled. Reef safe and peaceful, but a notorious jumper — a covered tank is essential.
Care guide
Keeping Purple Firefish healthy in a South African setup.
Tank setup
A minimum 100L aquarium suits Purple Firefish. Provide hiding spots and stable, well-filtered water; it suits a community setup.
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
Carnivore — small frozen foods. Feed small amounts it clears in a couple of minutes, and vary the diet.
Behaviour
Peaceful, shy; jumper. Watch it at feeding time and at lights-out to see its real temperament in your tank.
Tankmates
Choose tankmates of similar size and temperament with the same water needs. Avoid fin-nippers and anything large enough to eat it.
Breeding
Breeding success with Purple Firefish depends on the line and water chemistry; ask your shop about proven pairs.
