Southern redbelly dace prefer the headwaters of clear, rocky streams, with spring-fed
pools. They are often commonly found near the sources of springs. They are is distributed throughout the range from the
southern Great Lakes and Mississippi River drainage, south to the Tennessee River
drainage. Isolated populations are in Kansas, Oklahoma, Colorado and New Mexico.
The Southern redbelly dace is one of the most strikingly beautiful
fish around. Its body is elongate and almost cylindrical.
There are two distinguishing characteristics which set it apart from
the other minnows. The scales are minute, almost requiring
magnification to be seen. The coloration is unique. A cream-colored
lateral band is layered between dark bands on the sides. The top dark
band starts at the edge of the opercle and turns into a series of spots
on the caudal peduncle. The lower band encircles the snout and ends in
the basicaudal rays of the tail. Black dots appear along the back
before the dorsal fin, and the mid-dorsal stripe may also appear as a
series of dots. Males exhibit carmine splotches on the chest, chin,
belly, and on the base of the dorsal fin, and their fins are bright
yellow. Females vary from plain to washed with pink. The snout is blunt
with a terminal mouth, in which the upper jaw slightly protrudes past
the lower jaw. Presence of a barbel is unusual, but at least one
population has been found which has barbels on each side of the jaw.
There are from 65 to 90 scales along the incomplete lateral line. The
pharyngeal formula is 5, 5, and the teeth are slender with slight
hooks, and occasionally a pattern of 5, 4 may be present. The dorsal,
anal, and pelvic fins contain 8 rays, and the pectorals have 14 or 15.
The intestine is long, consisting of two coils and a loop with a black
peritoneum.
The southern redbelly dace inhabits the clean, cool headwaters of
small streams. It is a secretive fish seeking escape cover under
overhanging banks or other structures. This fish is closely associated
with permanent spring flows, which also provide micro-habitat for various
scattered populations.
The Southern redbelly dace, Phoxinus erythrogaster, has been found spawning in a Wabaunsee Co. KS stream on a sunny afternoon in April. The water temperature of the stream was 64
degrees F. Dace were spawning in an area where, a few weeks earlier, male Stonerollers, Campostoma
anomalum, c.f., were showing signs of nest building.
Spawning of Southern redbelly dace occurs from May through July over
silt-free, gravel bottomed riffles. The nests of other stream minnows
may be utilized for egg deposition. Spawning takes place in schools
with 2 males usually accompanying a female. Egg deposits vary from 200
to over 6,000 eggs.
This fish is primarily a vegetarian feeding on
plant material and bottom slime. Adults may reach 3 inches in length.
These minnows are difficult to keep in an aquarium, but the effort is
rewarded by the dazzling color display.
Keep at least 6 per tank. They really like stronger waterflows. Tank heaters not usually necessary and can wash out their colors. Can be aclimated away from live foods. Can live between 3 and four years.
The southern redbelly dace was originally listed in the genus Chrosomus, but it is currently in the genus Phoxinus, which links the native genus to the old world genus of the same name.
