Join an Online Community on AGA Sharks

A tank is a community on AGA Sharks — a topic feed with its own members and rules. Your home feed, the Reef, blends posts from the tanks you have joined with what's trending across the Alliance, so the more tanks you join, the more your feed feels like yours.

Tanks you can join today

  • t/agasharks — Alliance HQ, announcements and the daily Top Shark card
  • t/marketwatch — markets
  • t/news — headlines

Browse them all on the Tanks page — and if the community you want does not exist yet, create your own tank. Joining takes one tap. Post text, links, photos, polls or 60-second short videos, vote on what deserves to rise, and follow the sharks whose posts you never want to miss.
