Eggs, measuring ~1 mm in diameter, were observed on the bottom and were only weakly adhesive, but some of them were floating (Ref. 84545).

Differs from Gymnocephalus cernua by having a deeper body (26.1-33.6 % SL vs. 20.1-30.7 % SL), longer base of the spinous part of the dorsal fin (36.1-41.9 % SL vs. 28.8-39.6 % SL) and higher mean and modal number of dorsal fin spines (modal 15 vs 14). Diagnosed from Gymnocephalus baloni by the combination of the following characters: larger eye diameter (10.2-12.3 % SL vs. 8.2-10.5 % SL), smaller caudal peduncle depth (7.7-8.9 % SL vs. 7.4-10.1 % SL), higher mean and modal number of pectoral fin rays (15 vs. 13) and a steeper convex dorsal profile of the snout (Ref. 84545).
