It feeds by picking invertebrates from the silty layer that covers the sand in many places (Ref. 5595). Stauffer, J.R. Jr., A.F. Konings and T.M.

It is distinguished from P. williamsi by the absence of two horizontal lines of black dots on the flank (Ref. 119458).Description: Medium-sized mbuna, ovoid body with greatest depth at about 6-7th dorsal spine (Ref. 119458). Dorsal body profile with gradual curve downward, more acute towards caudal peduncle; ventral body profile slightly convex between pelvic fins and base of rays of anal fin with upward taper to caudal peduncle; dorsal head profile round, with continuous curve between interorbital and dorsal-fin origin; horizontal eye diameter greater than preorbital depth; eye, along horizontal axis, in anterior half of head; snout straight; jaws isognathous; tooth bands with 4 rows in upper jaw and 3-4 rows in lower; teeth in anterior outer row bicuspid with posterior lateral teeth primarily unicuspid, and teeth in inner rows tricuspid (Ref. 119458). Dorsal fin with XVII-XIX spines and 8-9 soft rays; anal fin with III spines and 8-9 soft rays; first 4-5 dorsal-fin spines gradually longer posteriorly with fourth spine about 1.5 times length of first; last 13 dorsal-fin spines increasingly longer posteriorly with last spine longest, about 2 times length of first; soft dorsal fin with subacuminate tip, third or fourth ray longest, to approximately 1/4 length of caudal fin; anal-fin spines progressively longer posteriorly; 3rd or 4th ray longest, to base of caudal fin in both sexes; 1-3 small yellow spots on posterior part of anal fin; caudal fin subtruncate to slightly emarginate; length of pelvic fin to first spine of anal fin; pectoral fin short and paddle-shaped, length to vertical line through base of 10-11th dorsal-fin spine (Ref. 119458). Flank scales ctenoid with abrupt transition to small scales on breast; 32-33 lateral-line scales; cheek with 3 rows of small scales; caudal fin with tiny scales to 1/4 length; no scales on other fins (Ref. 119458). Gill rakers on first ceratobranchial 10-12 (Ref. 119458).Colouration: Recently captured fish with gray head, white gular region, and black opercular spot; laterally gray ground colouration; scales with green outline; breast and belly gray; dorsal fin pale yellow to hyaline; caudal fin with two ventral rays and membranes black; remainder clear with faint white spots; anal fin black with white marginal band; 1-3 yellow ocelli in rayed portion; pectoral-fin rays clear; pelvic-fin rays black anteriorly, remainder clear (Ref. 119458). Colouration of female similar to male (Ref. 119458). Stauffer, J.R. Jr., A.F. Konings and T.M.
