Hi Paul.
Welcome to the project, and welcome to a new UK member.
Steve at Aqualife has imported P. ornaticauda for a couple of members of the project here in the UK before, he generally knows what he’s doing. As with most people, we had limited success with them.
The fish in the pictures do look like extremely stressed P. ornaticauda though. They have a different body shape to most other species of Parosphromenus. Much more cylindrical, the same as their close relative, P.parvulus.
