I know that fangtooths in particular aren't as much interested in shrimp but still do eat it nonetheless, the lobster is about i believe 4 or 5 inches in the picture (the lfs is far away so they usually send pictures of the new stocks on WhatsApp) the morays I intend to keep with the blue spiny lobster (panulirus versicolor) with a highfin moray (gymnothorax pseudothyrsoideus) and gray face moray (gymnothorax thyrsoideus) the eels are about 16 to 18 inches, particularly small, I will not take a risk, if there is anyway that they both can harm eachother especially if there's any damage which can be done to the eels the tank is a 60 gallon it's temporary for the eels but I would say permanent for the lobster incase if there is no issues
