Pico Reef

A tiny saltwater reef tank under 5 gallons - the smallest end of the marine hobby, requiring exceptional stability discipline.

Difficulty: Advanced Tank Size: 2g+ Recommended: 5g

📖 Overview

Pico reefs prove that reef-keeping can happen at desktop scale. Trade-off is parameter instability - a tiny tank fluctuates fast. Usually houses just shrimp, coral frags, and one small clownfish or blenny.
