Parosphromenus pahuensis
Parosphromenus pahuensis
IUCN: EN (Endangered)
Found in Kalimantan. Distinction between sexes of this species can be difficult as the colour patterns on the fins are similar for both male and female. However, the males fin colouration is a bit more distinct and colourful than the females, and the dorsal fin is slightly more pointed, which is recognisable from sub-adult age. Threatened due to agriculture and land development.

Parosphromenus linkei
Parosphromenus linkei
IUCN: EN (Endangered)
An Indonesian endemic found in the lowlands of central Kalimantan. The male of this species is generally bigger than the female and has a longer dorsal fin. Despite a wide natural distribution, the species is under a high level of threat due to draining of their native habitat for agricultural purposes and removal of natural vegetation.

Parosphromenus bintan
Parosphromenus bintan
IUCN: VU (Vulnerable)
This species is endemic to Bintan Island. When the male is in breeding condition, his fins will have a blue band and the edges have a thin white like with darker colours between. The female appears similar to other species, creating a risk of hybridisation in captivity if the aquarist is not careful.

Parosphromenus phoenicurus Indragiri
Parosphromenus phoenicurus Indragiri
IUCN: CR (Critically Endangered)
It’s IUCN rating is owed to its incredibly limited range in a single blackwater swamp in Sumatra. Wild specimens measure around 3cm. The most striking difference to other similar species is the caudal fin which deviates slightly. It is considered one of the most attractive of the liquorice gouramis.

Parosphromenus deissneri
Parosphromenus deissneri
IUCN: EN (Endangered)
Found only on Bangka and Belitung, this is one of the largest liquorice gouramis measuring up to 5cm in length. In breeding condition, the male is easily identified compared to other species by his one centimetre long, triangular, black caudal filament. They have a very limited range, making their threat of extinction more likely.

Parosphromenus filamentosus
Parosphromenus filamentosus
IUCN: EN (Endangered)
Occurs in central Kalimantan however the true extent of its range is unknown. Despite this, the threat level it faces is high due to the level of deforestation in its current known range.The caudal fin is characteristic to the species, being extended with an inner area of red/brown into black into a thin white/blue tipped edge. This makes this species visually quite distinct compared to other species of liquorice gourami.

Betta miniopinna
Betta miniopinna
IUCN: CR (Critically Endangered)
Endemic to Bintan Island in Riau Province, it is only known from a very small number of localities. They can measure up to 3.5cm long. Typical for these types of fish, they can survive up to several weeks in moist leaf litter during periods of no rain. They face heavy threats of habitat destruction as their home island is developed for tourism resulting in peat swamps being drained and forests cut down to make way for hotels and golf courses.
