Platinum Dragons

 is a Polyrhachis Ant colony that lives in El Dragon Island with various other animal inside the Paludarium.

History
The colony was founded after Mikey Bustos discovered the Black Dragons had escape from Paludarium. However, the colony wasn't healthy at all. It had been infested by Phoretic Mites, the same thing that happens to Golden Empire last year. However, he decided to put it inside and allowing the colony to flourish in hoping the parasitic Arachnida to leech out from the body of the ants.

In late July 2018, the mites had dropped off the bodies of ants and live out at the soil of the island.

Trivia
The name might be a reference to the Pokémon Platinum for the legendary pokémon as the Dragon trio.
