The Fountain Darter

Fountain Darter is a tiny Texas fish dependent on spring-fed habitat in the Comal and San Marcos systems. Clear water and submerged plants are central features of its home.

Spring Habitat

The fish occupies vegetation in spring outflows with relatively stable natural temperatures. Adequate spring flow supports both its underwater cover and water quality. Downstream stretches can differ in temperature and plant conditions, so the two river names do not describe uniform habitat.

Feeding and Eggs

Small crustaceans and insect larvae provide food. Adhesive eggs are placed among moss, algae and other submerged vegetation. Spawning can continue through much of the year in suitable spring habitat, while more variable downstream settings can produce stronger seasonal patterns.

Recovery History

The Comal population disappeared during the prolonged cessation of spring flow in 1956. Fish were reintroduced there in the 1970s. That history illustrates the importance of spring discharge to a species whose entire adult body is only a few centimeters long.

Spring Flow Matters

Stable spring habitat includes flowing water, suitable temperatures and underwater plants. A clear-looking pool alone does not describe all of those requirements.
