Afraid I've got you all here boys. 
That there is 1 Male (back in the top photo, and in the 2nd) and 1 Female (front of the 1st photo)
Worms on the head and cheeks (although, a very faint colour, possibly down to photo) trailing dorsal fin.
Hero Efasciatus if your looking for the latin names. Not to be confused with True Hero Severus.
Find it hard to believe your having problems getting sevs in Portsmouth. Some really nice (and rare) specimens poking around up north
Best of luck with them.
Watch for aggro from your male. looks like he's had a few digs at your female in the past.
Cheers
