The temperament of this species is amongst the most placid
of all triggerfish and thus it is highly prized by aquarists. It is possible
to house a male specimen with at least one female given an aquarium of
There are several references to the “invertebrate compatibility” of
this species in the literature. However, this is too broad a term and
could lead to confusion. The blue-throated trigger feeds mainly on
zooplankton in its natural environment and so arguably has less inclination
to do the damage to rockwork, or indeed other aquarium inhabitants,
that many other members of the triggerfish family seem to enjoy. Small
specimens in a reef situation are unlikely to do any harm to sessile
invertebrates, shrimp, urchins or crustaceans. However, large individuals
do present a threat to crustaceans and potentially urchins so perhaps
the best way to describe their suitability for reef aquaria is “sessile
invertebrate compatible” – but keep an eye on those shrimp!
A female specimen. She lacks the blue throat and is considerably
smaller than the male.
Given the relatively large potential size this species should be
kept in aquaria with sufficient capacity to hold the full-sized fish
plus care should be taken with smaller, less robust fish which may
be out-competed for food when the blue-throat gets over its initial
shy phase. The relative timidity compared to many other triggerfish
species may be reflected in the fact that this species is seldom
seen in depths less than 20 metres. Thus it is a fish which may prefer
slightly lower light levels than found in many marine aquaria.
So what will you have to pay for such a fish? Well, males certainly
command a high price but then they are generally larger than females
and so shipping costs will be higher. They are also relatively less
abundant which will also have an effect on their end price. An adult
male in full colouration will set you back around £65-£75
on average. Females change hands for approximately £35-£50
depending upon their size and where they have been sourced from.
