» Life History
Fountain darters are known primarily from spring dominated aquatic habitats dominated by submergent macrophytes and algal mats. Eggs are attached singly to low dense vegetation, typically filamentous algae (Rhizoclonium sp.), creeping primrose-willow (Ludwigia repens)and in the upper San Marcos River on Hydrilla verticillata (Phillips et al 2011, Transactions of AFS).
Fountain darters prey on small microcrustaeans, shifting to slightly larger prey as they grow.
Movement / Home Range
Fountain darters have high site fidelity, moving on average (± SD) 10 ± 17 m during 1 year period (Dammeyer et al 2013 Transactions AFS 142:1049-1057)
Eggs are attached to submergent macrophytes and algae. Swim-up fry are about 4 to 5 mm. Fountain darters mature in about 8 to 12 months, when they attain about 18 - 20 mm total length. Reproduction is year round but productivity appears to be higher in the April - September period.
