lol i would consider these small to medium-sized catfish. I would never own a TRUE GIANT catfish like a Mekong or a Paraiba or a Jau or a Wallago. I have been considering a a native wild-caught Flathead for a Dovii tankmate but i have to see what's in the budget for next years' tank upgrade. I already know a 2 foot Channel Cat will be bombarded relentlessly by a Midas cichlid half it's size. I don't expect much more progress with a Wolf and a Flathead either.... but i can try and keep close watch if I can get a humungous tank soon. Not really practical to house a 125lb fish though.....not really practical to house a single male Dovii either LOL. We'll see what direction the game of life takes me
