| − | + | |sexing=:Once sexual maturity is reached, males will retain the "eye spot" near the base of the caudal fin. Females will lose this. Males will often have green-coloured ventral fins. | |
| − | + | |tank_compatibility=:Bowfin may take food from any area of their space. They have a relatively small mouth with a primitive design, but this mouth is extremely powerful and contains sharp, conical teeth. Be wary of keeping small fishes together with the Bowfin as it can be a voracious predator. | |
| − | + | |diet=:When available, Bowfin will almost always show preference to small crustaceans such as shrimp and crayfish. They may also eat frogs and other fishes. Young individuals will readily take insects as well. | |
| − | + | |feeding_regime=:Feed once or twice a day depending on selected diet. | |
| − | :Once sexual maturity is reached, males will retain the "eye spot" near the base of the caudal fin. Females will lose this. Males will often have green-coloured ventral fins. | + | |environment_specifics=:Bowfin can grow to be quite large, so a large tank is needed. While a well-oxygenated tank is a fine thing to have, it is not required for the Bowfin. Bowfin are non-obligate air-breathers and can choose to either diffuse dissolved oxygen into their blood via their gills or they can diffuse atmospheric oxygen into their blood via a highly vascularised air-bladder. The latter is accomplished by taking "breaths" at the water surface. |
| − | + | |behaviour=:Bowfin are quiet fish to keep - except at feeding time. They will actively seek out their food using sight as much as a well-developed sense of chemoreception, or "smell." Their pre-maxilla is included in their gape (as a salmon's) and Bowfin need to grab their food. Sharp, conical teeth hold the food in place while a single, gular plate is used to crush it. They will seek food in any area of their tank. | |

:Bowfin receive their name from a long dorsal fin that they use to make slow backward and forward movements by undulating it up and down their back as a "bow." | :Bowfin receive their name from a long dorsal fin that they use to make slow backward and forward movements by undulating it up and down their back as a "bow." | ||
| − | + | |identification=:Bowfin can be identified by a long, single dorsal fin atop a cylindrical body with an asymmetrical caudal fin. The pelvic girdle is posteriorly placed. Two stubby tubercles sit at the end of a short snout. All individuals are brown in colour; juveniles, however, will often have strong reticulations throughout the body and have a caudal eye spot. | |
