Protomelas sp. 'steveni black belly' Bandawe Point
Genus:
Protomelas
Biotope:
Sediment-free rocky habitat in the upper regions,
occasionally also in sediment-covered rocky areas.
Most common at Kande Island and Bandawe Point,
where it appears to replace P. taeniolatus.
Geographic distribution:
Northwestern coast of Lake Malawi,
between Mdoka and Kande Island (Malawi).
Typical adult size:
Males up to about 17 cm total length;
females rarely exceed 12 cm.
In aquaria may grow slightly larger.
Sexual dimorphism:
Juveniles similar in appearance.
Adult males develop breeding coloration and a distinct
dark ventral region.
Fry a few weeks old show bright yellow anal and ventral fins.
Recommended aquarium size:
A minimum aquarium volume of 300 l and a tank length
of at least 130 cm are required for one dominant male with
several females. Significantly larger aquaria are necessary if
more than one adult male is to be maintained.
Aquarium setup:
Provide rocky structures and sand substrate.
Avoid tankmates that resemble the male breeding coloration to
reduce aggression.
Diet:
Likely feeds primarily on algae from the aufwuchs,
possibly supplemented with invertebrates.
Moves rapidly through the habitat, picking selectively
at specific sites.
Breeding:
Territorial males defend sites between or on top
of rocks, or on sand beneath overhangs.
Spawning not directly observed.
Females mouthbrood and guard free-swimming fry
for about three weeks after first release.
Aggression:
Males strongly territorial in the aquarium.
Avoid housing with similar-looking Steveni-type species,
especially P. taeniolatus.
Special notes:
Distinguished from P. taeniolatus
by its dark belly and steeper snout profile.
Rare over much of its range but locally common at
Kande Island and Bandawe.
Possibly ecologically separated from
P. taeniolatus through differences in feeding efficiency
or diet preference.
