Parosphromenus opallios
Kottelat & Ng 2005
Première description : diagnoses of six new species of Parosprhomenus (Teleostei : Osphromidae) from Malay Peninsula and Borneo, with notes on other species. The raffles Bulletin of Zoology 2005 Supplement No. 13: 101 – 103.
Caractérisques : Longueur totale maximale 3,5cm. Structure dorsale : XI-XIII, 6 – 8, total 18 – 19, nageoire anale XI-XII, 10 – 11, total 21 – 23. Le mâle en parade est souvent très foncé, avec des variations ( dépendant de la localité), les nageoires impaires présentent habituellement des zones rouges vives, turquoises claire, et de couleur bleue, les nageoires ventrales sont tachetées avec des filaments brillants, les femelles non stressées, outre la couleur du corps plus pale et le manque de brillance des liserés des nageoires impaires, et spécialement par une nageoire dorsale moins pointue, sont souvent plus rondes. Le corps apparaît souvent légèrement compact.
Espèces similaires : Pour les mâles, il est facile de les confondre à première vue avec les espèces aux nageoires partiellement rouges du groupe bintan-harveyi, comme rubrimontis ou alfredi, mais après une observation de plus près, ils sont distinguables, en condition d’excitation, par la distribution caractéristique des couleurs. Chez les femelles, les poissons peuvent certainement être facilement confondus avec les autres espèces du groupe bintan-harveyi.
Découverte /Distribution : Bornéo : Kalimantant Tengah, zone de Sukamara, le bassin de la rivière Jelia Bila, à Kalimati dans le bassin d’Arut (région de Lamand) près de Pangkalanbun et dans la rivière Benipah au sud ouest de Kubu. H. Linke mesura une conductivité de 9µS , une valeur maximal de 1°d KH et GH and un pH légèrement en dessous de 4,0 dans une eau noire. Les poissons étaient trouvés dans les zones littorales peu profondes et très végétalisées. L’espèce cohabite dans certains de ses habitats avec P. linkei. Encore aujourd’hui, une zone beaucoup plus étendue est connue par rapport à ce qu’il a été supposé avant (« Sukamara ») il est possible, voir probable que des formes différentes, qui varient considérablement en ce qui concerne la coloration, montrent la présence de variantes, dont l’identité ou séparation génétique sont encore complètement inconnues
Menace : Très haute, comme pour beaucoup d’autres espèces, à cause de la destruction de la forêt tropicale. Cela est vrai essentiellement pour les plaines alors que la variabilité de l’espèce est évidente et indique probablement une division déjà présente dans deux populations génétiquement séparées.
Découverte /Première importation : Collectés pour la première fois par Kubota, Linke et Al en 1990. Probablement plus tôt, mais alors non reconnu comme une forme distincte, le poisson était nommé « P. spec. Of Sukarma » jusqu’à sa première description en 2005.
Commerce : L’espèce était initialement connue seulement par des importations privées, mais a été commercialisée à petite échelle récemment.
Soins /Elevage : pas différent des conditions standard d’élevage. Une densité faible en germes est très importante, qui peut être obtenu par une faible valeur de pH (max. 4,5) et la présence de substances humiques. Les échecs dans l’élevage sont probablement dus aux différences des populations, l’origine est encore inconnue.
Comportement /Particularités : Constructeurs de nids dans des cavités. L’espèce fait partie des espèces qui paradent la tête vers le bas. Il est surprenant que le poisson naturellement très coloré perde occasionnellement ses intenses couleurs, spécialement après plusieurs générations. Cependant, le plus souvent, les mauvais paramètres de l’eau en sont la raison.

For a long time we have here at PP not had a photo of P. opallios. This and the following photos is assumed to be P. opallios, based on the photo and the information that they have come together with an import of P. linkei. As these two species lives close by each other in the Southern part of Borneo, Indonesia, — we assume with high certainty that this is opallios. Copyright Anh Tran, Black Water Aquatics
