Care Tips for Saltwater Invertebrates

  • Maintain stable salinity (1.024–1.026) and temperature (76–80°F)
  • Avoid sudden parameter changes — invertebrates are sensitive to copper and ammonia
  • Provide plenty of rockwork and sand for natural foraging
  • Feed small amounts of marine snow, phytoplankton, or leftover fish food as needed

Invertebrates not only help keep your reef clean — they make it come alive. From playful shrimp and industrious snails to decorative feather dusters, these tiny reef helpers are an essential part of a thriving saltwater aquarium.


Invertebrate FAQs

Are all invertebrates reef-safe?
Most are reef-safe, but a few species (like some large crabs or predatory starfish) may disturb corals or small fish. Check each listing for compatibility notes.
How many invertebrates should I keep?
A general guideline is one to two invertebrates per gallon for a balanced cleanup crew. Adjust based on tank size, algae growth, and bioload.
Can invertebrates live with saltwater fish?
Yes — most invertebrates coexist peacefully with reef-safe fish. Avoid housing them with aggressive species like Triggers or large Puffers that may prey on them.
