In the aquarium
Datnioides polota is an ambush predator that needs a large tank, since it reaches about 12 in. Keep it with tankmates too big to swallow. It takes live and meaty foods and can be trained to frozen fish. Brackish conditions may suit it, since it ranges into estuaries; FishBase gives 22 to 26 C.
Conservation
The IUCN Red List lists Datnioides polota as Least Concern, assessed 9 August 2019. FishBase notes it is marketed fresh as a food fish.
