Choosing the right saltwater invertebrates for your tank
Invertebrates are more sensitive to water quality than most fish, so add them only to a cycled tank with zero ammonia and nitrite, stable salinity around 1.024-1.026 and a temperature of 72-78°F. Acclimate slowly, ideally by drip, and never use copper-based medications in a tank that houses invertebrates. Shrimp and crabs molt as they grow and benefit from stable calcium and iodine levels.
For a clean-up crew, combine grazing snails such as turbo, trochus and cerith with nassarius snails for the sand bed and a few small hermit crabs. Cleaner, peppermint and fire shrimp add color and service, while starfish and urchins suit larger, mature reefs. Check compatibility before ordering: wrasses, hogfish, triggerfish and puffers eat many invertebrates.

Frequently asked questions
How do I acclimate saltwater invertebrates?
Float the bag to match temperature, then drip acclimate slowly so salinity changes gradually before releasing them into the tank.
Are saltwater invertebrates reef safe?
Most snails, shrimp and small hermit crabs are reef safe, though some large crabs and starfish can bother corals, so research each species.
Which invertebrates are best for beginners?
Hardy snails, small hermit crabs and cleaner shrimp are the easiest starting points for a new reef tank.
