NANFA-- Newbie Question - Slenderhead Darters

Hand a wonderful time tagging along with an Illinois-Indiana group along
with Dr. Page and some of his students to the Little Wabash River and the
Embarras River last Saturday. Neat people, all. Four 3" slenderhead darters
followed me home.

They seem comfortable under some driftwood and Najas while a small power
filter riles the water. They greet frozen glassworms casually, live daphnia
with gusto.

Although they show different girths from an overhead perspective, they all
display the orange dorsal seen in a picture of a breeding male. Is there
much sexual dimorphism in the species or am I the proud owner of four males?

Just for the record, what mode of spawning do they use? Would a box of
gravel placed under a filter flow work for a spawning spot (if one had
members of both genders)? They seem to get along, but is their 10 gallon
tank too small for comfort? Are there fishes which could cruise the open
area above them or are the darters likely to pick on them? What other food
items do they favor?
