From Peru we occasionally receive beautiful young Metynnis. We have not yet been able to identify them; they either belong to a scientifically undescribed species or represent a local form of M. maculatus. They certainly belong to the species cluster around Metynnis maculatus and we think that the final size, similar to M. maculatus, is around 20 cm. Conspicuously at the young animals, which are 4-6 cm long at present, are the particularly large spots at the body. They also have a deep red anal fin and a strong orange-red zone on the gill cover. The larger the animals become, the more points they develop. However, we have not yet had these fish larger than 8-10 cm with us, so we do not know what the final coloration looks like.
It is absolutely necessary to keep these silver dollars in groups of at least eight – better more – specimens. They are lively swimming animals, which require a relatively large aquarium. Planting is usually not possible, as plants are generally seen by fish as a food supplement.
For our customers: the animals have code 268072 on our stocklist. Please note that we only supply the wholesale trade.
