my fish can see me going to the freezer.. and do the same.. if any men come in they always expect food.. it could be because men wear darker, plainer clothes and they associate it with dinner.. where as if my wife goes in they swim away.. its funny to watch..
what i found worked for problem feeders is to feed then there favorite foods at lunch and dinner.. and feed the foods you want them to eat in the morning when they are really hungry..within a week they should be just as excited at the yellow tetra can
also try earthworms, frozen brineshrimp, white mosquito larve, frozen discus food mixes.
i always feed at least 1 serving of dry food like tetra prima for protein..
Hope that helps
