The tank is 24*16*19 so maybe to small for a dwarf angle. I was thinking my 2 clarkii's, a six line wrasse, some kind of prawn goby to go with my pistol shrimp just not sure which one yet, starry blenny, a tail spot, some kind of hawk fish, ref scooter dragonet. Not all of them but just some thoughts I had. Hoping to find one show stopper just not sure what.
Standard disclaimer, I have not kept these fish but I've done absurd amounts of research on the ones I'll mention. I'm also new to saltwater and have yet to get a feel for what stocking levels are acceptable for different sized tanks so the list below are possibilities to mix and match not to have them all at the same time
Sixline wrasses have really bad rep, a recent thread somewhere on here asked what fish you'd never have again and sixline wrasses are a sizable portion of the listed fish. The pink streak wrasse is probably the best alternative in that they look similar (even cuter in my opinion with their bug eyes) and are supposedly one of the most peaceful wrasses. Although any wrasse small enough to fit in your tank will be competing with the dragonet.
Your stock list seems to be a little mixed with peaceful (Tailspot blenny, dragonet, prawn gobies) and aggressive (dwarf angels, sixline wrasse, hawkfish, clownfish) and typically mixing these two groups isn't advised. Also keep in mind if this tank has coral that most dwarf angels seem to go off the rails at some point or another and start snacking on polyps.
However like the six lined wrasse, some of the fish you like have peaceful alternatives, so a stocking list could include some of the following:
Pink streak wrasse instead of sixline
Unarmed perchlet instead of hawkfish
Tailspot or starry blenny (they are conspecifics so they might bicker, solved by picking your favourite one)
Dragonet (Provided you are prepared for the challenges/expenses of feeding them like adding a pod hotel or supplementing stupid amounts of pods and also wrasses would compete for pods)
Pistol shrimp and goby pair as long as your rock is secure and was added before the sand or secured via acrylic rods or something to that caliber. Otherwise you could be in for some rock slides.
One idea I saw on here for small to medium tanks that blew my mind was instead of focusing on that one awesome fish- to focus on a group of awesome fish. A group of select species of cardinals can make a fascinating display!
