How do you care for the bartlett's anthias?

Semi-aggressive; one of the more peaceful anthias.

Feeding

Carnivore.

Frequent feeds; refugium helps.

Tank and special needs

Plan for at least 265 litres of water (the care sheet says 70 US gallons).

Caves, strong flow.

Corals and invertebrates

None.

Which tankmates suit the bartlett's anthias?

Groups in a species-focused tank.

Suggested order in a mixed tank: add after the first peaceful fish.

More than one bartlett's anthias

Best kept as a group added at the same time, in a tank big enough for the group.

Other fish

Checked against the other 59 fish in this guide, assuming a tank big enough for both. Individual fish differ, so treat this as a starting point.

Usually fine together (59)

Invertebrates

Only the invertebrates with a known risk are listed.

Take care (2)

  • Tiger tail sea cucumberA stressed or dead tiger tail sea cucumber can release toxins that harm fish; cover pump intakes.
  • Sea appleA stressed or dead sea apple can release toxins that harm fish; cover pump intakes.

Corals and anemones

Only the corals and anemones with a known risk are listed.

Take care (1)

These checks follow the reasons fish and invertebrates clash: same species or genus, similar shape, mouth size, temperament, food, burrows, tank size and the order they are added. Individual animals differ; every source agrees on that.

Quarantine and health

As lyretail.

New fish are the most common way disease gets into a reef tank. Quarantine every fish in a separate tank before it joins the display, and choose a method that suits its tolerance of copper.

Captive-bred or wild?

Wild-caught.

Name note: FishBase and Wikipedia now place it in Nemanthias (Nemanthias bartlettorum).
