i have kept them with very large in comparison fish as follows large for them is 6" or larger with leopards 1.5" to 5"
aussie tusk -no problems 
purple tang -no problems
yellow tang - no problems
coris wrasse -no problems
panther grouper - problem ,he ate two leopards before i noticed it ,my bad for sure .
snowflake morey  -  no problems eel was 7" long 
banana morey  -  no problems eel was 6" long 
chestnut morey  - no problems eel was 6" long 
larger eels will eat them for sure even if its a mistake at night , i would not suggest any eels except for the banana and chest nut as they only get approx 6" long max .
large arrow crab  - problem as he caught and killed  one which i thought was quite 
impossible
they seem to have frogspawn ,torches and hammers figured out as i have many of them together and none have gotten caught ~yet ?
most larger fish that forge for algae and small foods such as angels should be okay IMO . the wrasses are pretty keen on where to go and when to hide  IMO .
if the fish is a fish that is large and swallows fish whole or like a large trigger that devours smaller fish i would certainly steer clear of them .
above  is what i have experienced personally .
oh yes leopards will jump so be careful but i think you know of that enemy !
