Muddy bottoms near river outlets at depths of 15–40 m.
Geographic distribution:
Recorded from the southern part of Lake Malawi, the eastern
shoreline, and Makonde in the northern section; although rare,
apparently distributed around much of the lake.
Typical adult size:
Up to 18 cm total length
Diet:
Likely feeds on snails and other hard-shelled invertebrates.
The stout pharyngeal teeth and thick lips suggest extraction
of snails from their shells.
Breeding:
Breeding males are mainly steel blue with a yellowish tail.
They appear not to be territorial.
Special notes:
Distinguished (together with M. balteatus) by its large mouth
with thick lips in which the teeth are embedded, stout
subconical pharyngeal teeth, and relatively large eye.
Differs from M. balteatus in the higher position of the
diagonal band, which does not cross the upper lateral line
below the spiny dorsal fin.
