Xiphophorus xiphidium

13. November 2020

The sword platy, Xiphophorus xiphidium, belongs to the top rarities among the live-bearers. The species is found on the headwaters of the Soto La Marina River and its tributaries, Tamaulipas State, on the Atlantic side of Mexico. The very pretty species remains with approx. 3 cm (male) resp. 4 cm (female) clearly smaller than the common Platy (Xiphophorus maculatus). Since both species can cross in the aquarium, one should refrain in view of the rarity of X. xiphidium from maintaining it together with its close relatives.

There are sword platies that look slightly different, for example those with a circular spot on the tail base, those with two small dots or with a crescent moon. Since these different colour forms also represent different populations, one should also pay attention to pure breeding on this level. Currently we have a variant without any tail pattern in stock.

Young males look very similar to females, also because they also have a “pregnancy spot”. Fully developed adult alpha males are very attractive fish with their tiger pattern.

The care and breeding of the sword platy is much more demanding than that of the ordinary platy. Above all, X. xiphidium should not be kept too warm, preferably at room temperature without additional heating.

For our customers: the animals have code 476702 on our stocklist. Please note that we only supply wholesalers.
