The position of the anal-fin gland can be seen as a pale gray-white oval area just posterior to the proximal end of the white pigment along the anterior border of the anal fin, especially in the upper male in the picture. Both males display the lateral-line pores and tubes outlined in black as occurs in live specimens.
