Historic Range: The historic range of the fountain darter included the sources, headwaters, and sections of the San Marcos and Comal rivers. Houghton Mifflin Company, Boston. 1995); E. fonticola hatches at the smallest total length, has
fewer numbers of preanal myomeres than any other Texas percid, and yolk
absorption occurs earlier than in members of Oligocephalus (Simon et

similar, but differ in that the former species has a short lateral line with
0-6 pores, 1 anal spine, and cross-hatching on upper and lower side, while
the latter species has a short lateral line with 0-9 pores, 2 anal spines,
black or brown dashes along side, and spots on upper and lower side (Page

water hardened eggs were heart shaped, slightly indented, vertically
compressed, demersal, and adhesive; eggs contained a translucent, pale
yellow yolk, a single oil globule (averaging 0.36 mm maximum diameter),
smooth chorion, wide perivitelline space, and were unpigmented; eggs
incubated at 20 degrees C began hatching on day 4 after fertilization and
