Overview

  • The skunk cleaner shrimp is the white-striped, antennae-waving shrimp of nature documentaries, famous for picking parasites and dead tissue from fish at cleaning stations.
  • In aquariums it does the same, with fish queueing and even opening their gills for service.
  • It is peaceful, reef-safe, and genuinely useful — but it is an invertebrate, and inverts play by stricter water-chemistry rules than fish.

Housing

  • Provide a stable, mature reef of 75 litres (20 gallons) or more with rockwork ledges and overhangs where the shrimp sets up shop.
  • Singles and pairs both work; skunk cleaners are simultaneous hermaphrodites, so any two adults form a pair.
  • Keep salinity rock-steady at 1.024-1.026 and temperature at 24-26C.
  • Sudden salinity or pH swings — including sloppy top-offs — are the main killer of healthy specimens.

Diet

  • Cleaning service plus scavenging covers part of the menu, but feed directly: sinking pellets, frozen mysis, and bits of meaty seafood.
  • A fed cleaner is a bold cleaner.
  • Expect shameless theft of food intended for corals and fish; many keepers feed the shrimp first so target-fed corals stand a chance.

Health

  • Acclimation is the make-or-break moment: drip-acclimate over at least an hour, because osmotic shock from quick transfers kills more cleaner shrimp than anything else.
  • Never expose them to copper-based medications.
  • Regular moulting is normal — a perfect, ghostly shell on the sand and a hiding shrimp for a day or two.
  • Failed moults point to unstable parameters or iodine-poor water; steady reef-standard maintenance prevents them.

Temperament

  • Completely peaceful and impressively bold, a settled cleaner shrimp rides hands during tank maintenance and inspects anything new.
  • The cleaning interactions with fish are mesmerising and genuinely beneficial.
  • It coexists with corals, snails, other shrimp species, and almost all reef fish.
  • Predatory exceptions — hawkfish, large wrasses, triggers, puffers — see it as lunch, so check the stocking list both ways.

A good fit for

  • Reef keepers wanting visible, useful invertebrates
  • Tanks with occasional fish-parasite pressure
  • Aquarists who enjoy interactive animals
  • Established systems with stable parameters

Common mistakes to avoid

  • Fast acclimation — the classic first-day killer
  • Copper medications anywhere in the system
  • Housing with hawkfish, triggers, or puffers
  • Salinity swings from careless top-offs
