Its coloring is pinkish to a purple brown coloring, the dorsal mantle is not fused with the head, and it has fins that are wide and short.[2] It has a length of 3.4 cm for males, and 6.3 for females.[4] Female A. australis lay their eggs in small clusters and then leave them unattended, and they may spawn several times in a year.[2]
