Quick answers

How does the "what should I keep" quiz work?

You answer six quick questions about your tank size, experience, and what you're excited to keep. We score every one of our fact-checked species against your answers and show the closest matches. It invents no new ratings — every match is derived from the same sourced care data on the species page, so it can never contradict a guide.

Is the quiz result a final decision?

No — it's a starting point, not a verdict. It surfaces species worth a closer look; then you read the full care guide (linked on every match) to confirm the real commitment — tank size, temperament, and cost — before you buy anything.

What's the easiest saltwater setup for a beginner?

A stable nano-to-standard reef with a captive-bred clownfish or two, a small cleanup crew, and a few forgiving soft corals (zoas, mushrooms, GSP) is the classic beginner path — low-to-moderate light, no demand on calcium or alkalinity. The quiz will steer a first-timer toward exactly this kind of forgiving stock.
