Above is the blind, cave form, the lower one is the normal surface dwelling form.
This fish, as you can see, has two forms in the wild, which are the same species. One is eyeless and pink, the other a normal fish.
This species, although a tetra, is not particularly gregarious, so does not require a group. But they will be fine in groups.
Females are larger and fuller bodied than males.
