For the Neons, Females are plumper when viewed from above and have a bent blue line. Males are slimmer with a straight blue line.

Is the White Tetra a white skirt or White Tip?
White Skirt: Female white skirts are generally larger than the males and have a rounder body. Females have short, rounded fins and the males have slightly longer, more pointed fins.

White Tip: Males have a flag like extension to their dorsal fin and an elongated pelvic and anal fin. Females have a rounder dorsal fin and are plumper and deeper in body.

CAE are too similar to tell in most cases.

If you have the scientific names for these fish, it would be helpful I can't find the info for Colombians, but if you search hard enough, it will turn up. Everything above was from the Fish Index.
