By comparison with some of the previous fish, the yellow tet is somewhat plain, but should not be ignored on that account.
The body colouring is silver-grey, overcast by a darkish yellow, which, when caught by a complementary angle of light, reflects a metallic iridescence. Just behind the head there are two vertical dark lines. It is an outstanding community fish, growing to 2.25 inch long, and has the virtue of being comparatively effortlessly bred, a reality which the beginner will appreciate.
