Your clownfish may host with the condy. I had one in my tank for several months and no hosting was occurring, then suddenly one day the only place the clown could be found was near the condy.
Use totes. Put shrink wrap around the tote to minimize splashing. Then put the lid on and shrink wrap over the lid. I have made two moves with my tanks so far (Michigan to Ohio almost 600 miles) and (Ohio to Indiana 190 miles) with no loss of life.
Poor water quality and stress are the reasons for the cloudy eye. Purely a guess, but I would say your tank is too small or you have not been diligent with your water changes especially with a messy eater like a trigger.
I would suggest to use hyposalinity to treat the trigger in a hospital...
