bowfin are part of an ancient order of fish. As a matter of fact, they are the only surviving member of their genus, making them a very special fish. It's rare in the pet trade because it's a native species which grows large, isn't outstandingly coloured, is an overly aggressive predator, and is very greedy, not something the typical aquarist with a mere 55g tank would want to buy. Also, if you're outside of it's natural range, then it would be considered a "rare" fish because they aren't commonly available through the pet trade and they are not available to catch.
Bowfins are not anywhere near related to gobies. They are partially cartillaginous, making them closer relatives to sturgeons and other primitive fish. However, as far as looks go, I'd say it looks like a cross between a snakehead and a wolffish.
