River Goby

Awaous banana is found in rivers and coastal streams from Florida to Colombia, migrating between freshwater and estuarine habitats during its lifecycle. It is a large and robust goby that can be kept in freshwater as an adult but may benefit from occasional brackish water access. It is primarily an algae and detritus grazer in the wild despite its size.

Water: 24–28 °C, pH 7.0–8.0, moderately hard freshwater or mild brackish. Tank: 300 L minimum; strong water flow; coarse sand and gravel substrate with large rocks. Feeding: Primarily herbivorous; algae wafers, blanched vegetables, and sinking pellets; accepts frozen foods. Behaviour: Territorial toward conspecifics; one per tank unless very large; vigorous excavator. Compatibility: Large, robust fish only; territorial toward other large gobies.
