Hi Minh;
WELCOME to CANREEF
Thats a pretty large load for a 65g. Or at least it will be when they all reach adult size. Those are a pair of pretty large triggers that usually prefer much larger tanks.
I,m not sure if triggers eat anenomes, but I would not put an anenome in a tank thats still a FOWLR. They are a bit harder to keep and require established reef aquariums. Like I said above, without the triggers that may be an idea, once the tanks more established.
Also once the fish get larger and the wet/dry is running, the nitates will increase. These will need to be removed by water changes or lots of algae filtration. This will also be hard on creatures like anenomes.
Usually if one has enough live rock or sandbed, other means of bio filtration are not needed. However its likely thats if your tank remains the same and with 60#,s of rock, the wet/dry will indeed help with the current bio load.
I,m sure more will jump in with ideas and comments and there is a lot of threads to read on here. But as I said above, welcome to our aquarium community.
