Planet Fish

From the fishroom

Planet Fish

Written at the tank, not off the box.

Planet Fish is an independent fishkeeping blog for people who actually run tanks — freshwater community, planted, brackish and reef. Gear guidance that reads like a well-kept logbook rather than a sales page.

The water we keep

A working fishroom

  • Freshwater community tanks
  • Planted aquascapes
  • Brackish setups
  • Reef systems

From a shrimp tank on a kitchen counter to a cichlid setup that has long since settled in.

Aquarists first, writers second.
