One of the undoubtedly most beautiful Rasbora species is R. kalochroma – and one of the most sensitive. They are typical black water fish which react very sensitively during the acclimatisation phase to increased bacteria contamination, which occurs almost inevitably in “normal” water. When we were now offered 1-2 cm long youngsters, we took advantage, because young fish are basically much more adaptable than adult animals. And the plan worked out! We now have very beautiful, well adapted Rasbora kalochroma in our stock.
The colouring of the fish in the photos is only a drab copy of the colouring they show in well equipped black water tanks; unfortunately you cannot photograph in such water or the colours would appear completely unnatural. In the past, R. kalochroma was considered to be the adult form of the dwarf rasbora (Boraras maculatus); however, the similarity is not very great from today’s point of view (see https://www.aquariumglaser.de/fischarchiv/boraras_maculatus_en/). Rasbora kalochroma becomes about 8-10 cm long and is a peaceful fish that appreciates the company of conspecifics.
For our customers: the animals have code 452300 on our stocklist. Please note that we only supply wholesalers.
