as for fish foods here are a few types i use
your fish list
owder blue tang,lawnmower blenny.(formula 2. frozen or flakes (i use frozen) emerald entrese(frozen)veggie flakes.kelp flakes both by omega one ,lifeline any foods meant for herbivores
coral beauty angel: pygmy angel formula also angel formula by ocean nutrition
not sure what a firefly fish is so im gonna roll it into this catagory although it may benefit from the other foods i suggested for your other fish. all will benefit from above foods if added to their normal diet by species
jawfish, clowns, firefly : formula one(flake or frozen) and other reef formulas by ocean nutrition. mysis shrimp chopped squid yum yums ,chopped clam yum yums.cyclopseze. i combine all frozen into one cup of water add garlic extreme and selcon let sit till thawed smash everything together and pour into the tank
this is done nightly
tangs and angels require more feedings that the other fish so i add pellets(therea+A non medicated antiparesitic formula)by spectrum every morning and lunch for my coral beauty(he hates flakes lol)
veggie flakes for lunch but all of my fish go crazy for the spectrum pellets they will also improve fishes natural coloring.i hope this helps
