About the Purple Firefish
Purple firefish are slender dartfish that hover above a favourite cave and disappear into it the moment something feels wrong. They are peaceful and easily intimidated by fast or aggressive tank mates.
Their tall dorsal fin and purple-yellow colouring make them easy to spot when comfortable, but a frightened fish may stay hidden and quietly miss meals.
Health risks to know about
Important concerns include jumping injuries, starvation from hiding, ammonia or nitrite poisoning, marine parasites, bacterial disease and wounds from harassment.
Rapid breathing, a hollow belly, damaged fins, repeated scratching or refusing to leave shelter for food needs prompt attention.
Tank, water and equipment
Use a mature marine aquarium with a completely sealed lid, several quiet caves, open hovering space, moderate flow and calm companions.
Measure salinity with a calibrated refractometer. Even small openings around cords and overflows need to be covered.
Food and feeding
Offer a complete small marine carnivore or planktivore food with suitable frozen marine foods.
Let food drift near the fish's cave and check that bolder fish are not taking every piece.
Behaviour, tank mates and enrichment
Hovering near shelter and vanishing into a cave when startled are normal. A new fish may need time and a quiet feeding routine before it stays visible.
Purple firefish are generally reef compatible, but unrelated adults may fight unless they are a compatible pair.
When to contact an aquatic veterinarian
Get help for gasping, collapse, severe wounds, major swelling, inability to stay upright, rapid unexplained deaths or a problem that continues after water parameters are corrected.
Test ammonia, nitrite, nitrate, pH, temperature and salinity whenever behaviour changes. Water quality is part of the medical history, so record results before contacting an aquatic veterinarian.
