Some time ago we were able to introduce you to the large, magnificent Mastacembelus unicolor, which was sent to us by mistake as M. erythrotaenia (see https://www.aquariumglaser.de/en/22-spiny-eels/mastacembelus-unicolor-2/). The animals at that time were too large for the photo aquarium, so we were only able to take photos from the regular sales tank.
Now we have been sent another specimen, but this time in the more manageable size of 25-30 cm, which still fits well in the photo tank. Apparently M. erythrotaenia and M. unicolor occur together in Indonesia, at least in some places. In principle, M. unicolor also looks like a M. erythrotaenia which lacks the red. The coloration of the pectoral fins also appears typical of the species. For more information on M. erythrotaenia see https://www.aquariumglaser.de/en/22-spiny-eels/mastacembelus_erythrotaenia_40_45_cm_arrived_en/ and here https://www.aquariumglaser.de/en/22-spiny-eels/mastacembelus_erythrotaenia_en/
For our customers: M. unicolor has 426725 on our stocklist. Please note that we only supply the wholesale trade. Only one specimen available!
