Can't see the picture.
If it's an African Lung, do not keep it with anything else. It WILL disembowel and otherwise maim anything you keep with it. Maybe not day 1 or day 15...but eventually.
Also, keep your fingers clear of it. They bite... A guy at an LFS in Sacramento got bitten by one...and it wasn't pretty (they grind in their throats).
Awesome fish. Highly intelligent. Live for 70+ years. Get 3+ feet long. Not a trivial commitment.
