Why Sea Life Planet
Most aquarium content online falls into one of two categories: generic listicles recycled across dozens of sites, or marketing copy from the stores selling the fish and equipment. Neither tends to mention the details that matter once the fish is actually in your tank — the real minimum tank size, the heater you'll actually need, or the tank mate combination that looked fine on paper but didn't work out.
Sea Life Planet is built around species and equipment guides written from direct tank experience, reviewed for accuracy against current sources, and updated when our understanding (or the hobby's best practices) changes. Every guide includes:
- Quick Facts — scientific name, realistic tank size, water parameters, and temperament at a glance
- Honest compatibility notes — including the combinations that don't work, not just the ones that do
- Direct answers to common questions — in a dedicated FAQ section on every guide
Where to Start
If you're choosing your next fish, start with Saltwater Fishkeeping or Freshwater Fish to browse guides by category, or jump straight to All Species Guides for the full list. If you're setting up or upgrading equipment, our Equipment Reviews cover the practical trade-offs — noise, reliability, mounting — that spec sheets don't.
