Associated Organisms



Difficult fish to keep in captivity, often related to the constant feeding requirements. Peaceful and placid, Tuka's can be kept in small schools.

Captive Care

Tank Size

200 litres

Water Flow

All types of flow are suitable. Medium flow is preferred in a captive environment, this helps keep food in suspension where the fish normally feeds, while reducing the amount of energy spent swimming against strong flow.


No specific lighting requirements. Newly introduce fish may benefit from subdued lighting for the first few days after introduced to the aquarium while they acclimatise to the new surroundings.


Pseudanthias tuka require regular feeding. They must be fed a minimum of three times a day, with small feeds five or six times a day preferred. Live foods such as baby or adult brine shrimp are good first food offerings, as initially they are often shy and difficult to get feeding. Food types should also include finely diced prawn, crab, mussel and other meaty foods, fish eggs, mysis shrimp, live or frozen brine shrimp, cyclop-eeze, spirulina and foods high in astaxanthin to help retain colour. A refugium may help supply a constant range of zooplankton such as copepods and amphipods.

Growth Rate

How quickly it will grow under various conditions.


Often suffers from bacterial, viral and fungal symptoms, likely amplified by its high dietary requirements not being met during shipping, handling and acclimatisation.


Pseudanthias tuka have a better survival record when introduced as a group or where similar natured fish already exist. Being sequential hermaphrodites (protandrous - born female, most dominate within school turns into male), groups introduced should be only female or contain no more than one male.




Avoid aggressive and boisterous fish.
