Inhabits spring, most adults occur in the upper meter of the water column and near the margins of the cattails or in the growth of cattails surrounding the spring. Few individuals are found in the open water column and near the substrate; relatively few fish are seen in the shallow marginal waters. Forms schools of at least 500-600 individuals .
棲息於泉水中, 大多數的成魚出現在水團的上面幾公尺與在香蒲花的邊緣的附近或在香蒲花叢中泉水周圍。 少數個體被發現於開放水域與在底部的附近; 相當少見的魚在邊緣淺水區中被見到。 至少 500-600個個體形成魚群。
