About the Royal Gramma
Royal grammas are small purple-and-yellow basslets that spend much of their time near caves and overhangs. They may hover sideways or upside down beneath rock, which can be normal for the species.
Captive-bred royal grammas are available in some markets. Ask the seller about origin and choose an alert fish that is already accepting prepared food.
Health risks to know about
Important concerns include ammonia or nitrite poisoning, marine parasites, bacterial disease, jumping injuries, poor body condition and wounds from territorial conflict.
Rapid breathing, repeated scratching, white spots, sores, a hollow belly or staying sealed inside a cave needs prompt investigation.
Tank, water and equipment
Use a mature, cycled marine aquarium with stable saltwater, plenty of caves, shaded overhangs, open feeding space and a tightly fitted lid.
Measure salinity with a calibrated refractometer. A specific gravity around 1.020 to 1.025 is a common starting range, with ammonia and nitrite kept at zero.
Food and feeding
Offer a complete small marine carnivore food with suitable frozen marine foods for variety.
Place food near the fish's chosen cave at first and confirm that faster tank mates are not taking everything.
Behaviour, tank mates and enrichment
Cave guarding and short warning displays can be normal. Avoid very similar basslets or dottybacks unless the aquarium and stocking plan are designed for them.
Royal grammas are generally reef compatible and usually leave corals and ornamental invertebrates alone.
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.
