Picked up 2 bowfin the other day from a local food market. Male around 20" and a female around 24". Currently in with some gator gars and an id shark that is ignored by all the other fish.
Picked up 2 more females both around 20". So far everyone is still getting along with only some minor fin nipping. Hoping it stays that way, but there are a lot of unpredictable preds in a relatively small volume of water. I also have another gator gar that will be added into the pond when it grows a couple more inches.
