Taxonomy & naming
Kottelat described this species in 1990 as Xenopoecilus oophorus, and it was later moved to Adrianichthys; the authority is therefore given in parentheses. It is one of four large Adrianichthys in Lake Poso.
Morphology
Adrianichthys buntingi are larger and more elongate than the lake's Oryzias, with an upturned mouth. FishBase gives a maximum of 3.5 in TL for this species.
Habitat
Known only from Lake Poso in Central Sulawesi; the type series came from the eastern shore between Tentena and Peura. FishBase describes it as a freshwater, pelagic fish and gives a pH range of 7.5 to 8.5 and a temperature range of 24 to 29 C.
Feeding
Diet has not been described for this species.
Mating
Courtship has not been described for this species.
Breeding
The epithet oophorus, egg-bearing, refers to the way females carry their eggs. FishBase says the eggs are carried in clusters between the pelvic fins, each attached to the body by 10 to 20 filaments, and protected there until hatching. Kottelat's paper presents this as a new reproductive guild. Clutch size and incubation time have not been published.
In the aquarium
Not kept in aquaria and with no hobby history.
Conservation
The IUCN Red List assessed the species as Least Concern in 2019. Introduced fishes, fishing and habitat change in Lake Poso remain concerns for the lake's buntingi as a group.
