No, archaea and protists are very similar but they do not live together in colonies. Protists is anything that doesn't fit in the category of the other kingdoms. Hope this helped!
Protists are simple microorganisms. They are unicellular or multicellular, but without specialized cells. They live in aquatic environments. they include fungi, plants, animals, bacteria, and archaea.
protists live in water
Some eukaryotic or prokaryotes live and function together in colonies.
Colonies
where do spore forming protists live
The most famous polyp colonies are called, "Coral".
The Cyanobacteria do live in water and are often found living together in clumps known as colonies.

Protists and bacteria are grouped into different domains because the Protists are more complex and contain a membrane backed nucleus which bacteria lacks. Furthermore, Protists eat bacteria and bacteria decomposes Protists. Bacteria is not made of cells and Protists are photosynthetic.
