I've read African lungfish can be extremely nasty but I still see people keeping them with monster fish on occasion. Im just wondering what fish would work best as a long term tank mate? I saw these photos of a guy on MFK keeping one with 2 Arowana, (Jardini + Silver) 2 Clown Knives, a Giraffe Cat and some large cichlids (Jaguar, Midas,Oscars) along with Tinfoil Barbs a large Pleco and even 2 RedTail Cats. I'm just wondering how long this would work if all fish were well fed and had alittle more space to swim around then the tank pictured? Could a tank like this really work stock wise? I'd love to pick up a marbled lung and will probably end up with one either way I'm just wondering if it would be possible to keep any fish with him or her? Or if I'd have to go with a solo tank, I didn't have a stock this large in mind maybe just something like a few large cichlids (the ones listed) or something like the giraffe cat or the CK idk? Just let me know! I could see it working if the fish were large enough I just don't want anyone getting hurt.
