tailspot blenny

The Tailspot Blenny is a small but mighty gem for reef aquariums. Its creamy, speckled body is punctuated by a distinctive dark spot at the base of the tail — the namesake mark that makes it instantly recognizable. Don't let its modest size fool you; this fish is a tireless grazer, spending its days perched on rockwork and methodically picking at microalgae and film algae with its comb-like teeth. Its manageable size and peaceful temperament make it one of the most reef-friendly and versatile blennies in the hobby.

Care Notes:

• Tank size: 10+ gallons — one of the few blennies well-suited to smaller reef systems
• Reef-safe: yes — completely safe with corals and invertebrates
• Excellent algae grazer — feeds on microalgae, film algae, and diatoms; supplement with nori or spirulina-based foods in low-algae tanks
• Peaceful with most tankmates; may show aggression toward other blennies or similarly shaped fish
• Loves to perch on rocks and corals, watching the tank with curious, expressive eyes
• A perfect choice for nano reef builds and community systems alike
