I mix san fran bay brine, v20 mysis, pe mysis ,v20 marine fusion, BA coralamino and selcon , then fill gummy bear molds , makes the perfect size for nano tanks and feeds everyone ! Nutrition is they key to success with all aquaria imo!
I don't mix my own but I do like the mermaids delight mix:
shrimp,cod,clam,squid,octopus, scallop,krill,brine,mysis,rotifers,seaweed, cyclops,oyster feast,decapsulasted brine eggs,copepods,phytoplankton, roe,vitamins, aminos,hufa
It has a bit finer texture than a lot of pre mixed foods which tends to break up better and there are no bits to big for little fish mouths
