I have a pair of Dwarf Gouramis (silvery blue) and they both hide all day they come out to feed but usually by the time they get to the food the 2 Dalmations and 2 Black Mollys have scoffed the lot.
kinda had the same problem when it came to feeding myfrogs, what i did in the end was used a straw to put live food down so it whent right to them, but ur dwarfs might getscared of the straw? worth a try if ur worring iguess.
I havent had that problem just yet as they are the only 2 fish in the tank other than a small pleco. I find sometimes that it takes them a while to know when they are getting fed.
