| Comments |
This fish is definitely seen at its best when in a larger shoal of at least 8-10 individuals.
A well established aquarium with good filtration is necessary to maintain them in good condition.
A second species (T. espei) has very similar markings and may also be sold under the name 'Harlequin'.
