I have one but no pics Care is pretty much same as any other bichir i think, its lower jaw so it gets large and can eat large prey. Growth slows once it hits about 8 inches i think. Looks a bit like an endli and a bit like a lap.
Ansorgii is the second biggest bichir (Still debating of which is the biggest pbb, ansorgii or congi). Ok back to ansorgii. Ansorgii my experience is the slowest lower jaw species that grows. My ansrogii took a while to get up 18". Also care is pretty much just like any other bichirs.
