Aquarium setup
A dedicated brackish aquarium. Mix marine salt with conditioned water and measure the result consistently; ordinary tonic salt is not a substitute.
Use 300 litres as the minimum planning baseline before allowing extra space for a group, tank mates, decor and swimming behaviour.
Hold temperature at 23–27°C and pH at 7.5–8.4; stability matters more than chasing a single number.
Design the aquarium around the recorded adult length of 22 cm, not the juvenile size seen at purchase.
Provide retreat areas and visual breaks while preserving enough unobstructed space for normal movement and feeding.
Filtration & waste
Moderate waste load (0.4 index): allow spare biological capacity and service mechanical media before flow is restricted.
Feeding
Offer varied, appropriately sized animal-based foods. Confirm that the fish is eating and avoid relying on a single food long term.
Observe
Confirm every fish reaches food and swallows it.
Control
Stop before leftovers can decay in the aquarium.
Review
Track body condition, waste and feeding response over time.
Behaviour & tank mates
Treat temperament as an individual assessment. Observe feeding and territorial behaviour, and keep a safe separation plan available.
No simple community match is approved in this profile. Plan species-only housing or obtain a specialist compatibility assessment before adding tank mates.
Health watch
These are risks to monitor, not diagnoses. Test the aquarium first and seek an aquatic vet or experienced specialist for severe, fast-moving or uncertain symptoms.
Watch for: A pinched belly, weight loss, weak feeding response or a fish being outcompeted at meals.
First response: Confirm that the fish accepts an appropriate food and can reach it without competition; seek help if weight loss continues.
Watch for: Hiding, faded colour, clamped fins, glass surfing, rapid breathing or appetite loss.
First response: Test water, review temperature and tank mates, reduce disturbance and correct problems gradually.
Before bringing one home
The established aquarium is at least 300 litres and matches the required brackish system.
Temperature and pH overlap the full 23–27°C and 7.5–8.4 ranges.
A suitable carnivore food is available and the seller can demonstrate that the fish is feeding.
Ammonia and nitrite test at zero, acclimation is planned and a quarantine or observation option is ready.
Every proposed tank mate has been screened for adult size, behaviour, feeding competition and water compatibility.

FishBase remains an editorial reference, but the useful species and care information is interpreted here so you do not have to leave FishSnap. Conservative planning baselines are labelled as guidance, not guarantees.
