Thanks, Darth!
jacob, don't think I have answered that. We have T5s & moonlights. We don't run both at the same time. I shoot with the T5s on & use the flash too to get as much light as possible. Things farther back or in weird spots in the tank don't come out as well. I'm lazy, I just use Auto and the "macro" (little flower) setting LOL. Sometimes I have to manual focus, like with the spaghetti worm legs. I've gotten to where I put it on manual, then just move forward or back until it's in focus & take the pic rather than try to adjust the focus ring myself.
Some of the shots up there, as mentioned, are shot under just the moonlights but using the flash. I get a good color pop that way while still lighting up the entire coral. Those are also using Auto. I try to get as much of the coral in the frame as possible, then crop if I need to to bring it in closer.
