The animals originate from Brazil. The animals put fish eggs(spawn) to come to very few and only few through.
It many L173 and L236 on the market offered, unfortunately are it not the genuine.
Brazilian Exporters like to use L Number like L173, L236 and L250 for unusually marked single fish of different species in order to fetch more money.
The L250 is very rare to hardly find on the market if one offers over 10000 - 20000USD/each.
