Bowfin mate once a year during the springtime. In the south, spawning can occur in late April, but in most cases it occurs in late May and early June. The male bowfin prepares a nest in shallow, vegetated waters. The nest is simply a clearing in the vegetation made by biting off roots. A slight depression is made so the eggs wont be swept away. A female lies on the bottom of the nest while the male circles her. They lie side by side and flap their fins. The female releases her eggs and the male releases his milt (sperm). More than one female can lay her eggs in a males nest, and females often lay eggs in several nests. It is common that there are eggs in different developmental stages in a single nest. The male guards his nest very aggressivly. There are often as many as three times more males than females in a spawning ground, which can lead to conflict (Scott Crossman, 1973). (Scott and Crossman, 1973)
The male takes care of all the parental investment duties. After fertilization the male guards the nest and keeps the eggs supplied with fresh water by moving his pectoral fins. Males may be so aggressive they will attack inanimate objects such as sticks, and have been known to leap out of the water toward invaders on the waters edge near the nest (Ross, 2001). When the hatchlings begin to swim the male guards them as well. The juveniles swim in schools guarded by the male until they reach four inches in length. At this time the young bowfin begin the solitary behavior of adults (Richmond, 1997). (Richmond, 1997; Ross, 2001)
I am sure that it can be done but the amount of space they require would be large goinging on this information
I have also see that when in is breeding season I think the males mouth goes bright blue
