Mimian Bladder Fish were a stingray-like GELF fish cultivated and eaten on Mimas and it's restaurants, therefore presumably eaten with Mimosian Anti-Matter Chopsticks and drank with Mimosian Telekinetic Wine. Arnold Rimmer pretended to be an officer and said he was off to try such Mimian/Mimosian cuisine to Dave Lister when he asked Lister (posing as a taxi driver in a stolen hopper) to take him to the red light district of Mimas. Rimmer claimed he wanted to try the Mimian bladder fish; an obvious lie since he had Lister take him to a droid brothel. (Infinity Welcomes Careful Drivers)
