Hello ,update on the wrasse, tried him, on brine shrimp and freshwater live shrimp ,not interested, hadn`t seen him for 36 hours as hes staying under gravel, dug him up this morning to see if hes still alive(don't want him polluting the tank) he looks fine stayed on the base of the tank for about 30seconds then buried himself again , unless anyone has any more suggestions I think I will have to let nature take its course, thanks for the help.
