Parosphromenus, para: Greek - in the side of.
Parosphromenus deissneri, come from very acidic and very soft water. They will not thrive in hard alkaline water for very long at all. Due to their small size and sedate lifestyle a group of about six to eight individuals can be kept in a 60 litre aquarium.
This can be a problem area with Parosphromenus deissneri because they never accept any dried food. Most specimens will only ever accept very small live food such as micro worms, cyclops and baby brine shrimps. Some specimens will learn to accept frozen food but this can't be relied upon.
Very peaceful but also quite timid, boisterous tank mates will increase their timidity to the point where they may refuse to compete for food so only small gentle species should be considered as tank mates. Ideally they should be kept in a group in a species aquarium or if it is the intension to breed them then keep a single pair with no other fish present.
Males have a white to blue edge on their dorsal, anal and tail, they also exhibit stronger colours although the latter cannot be relied upon.
Unlike a lot of other similar fish which are bubble nest builders Parosphromenus deissneri are cave spawners. The male does most of the brood care once the eggs have been laid. A well cared for pair will spawn with no special treatment.
The wild status of Parosphromenus deissneri has not been evaluated but the species is potentially under great threat due to having a very small range. Originally Parosphromenus deissneri was thought to be endemic to the small Malaysian island of Bangka but it has also been found on the neighbouring island of Belitung. The species hasn't spread beyond these two islands.
The name Parosphromenus deissneri has been wrongly applied by the aquatic trade. There are now twenty recognised species of Liquorice gourami. and until a few years ago the fish we commonly call Liquorice gourami found for sale was not Parosphromenus deissneri.
