If you included the species of fish, I could have given you an answer. =(

I do not know what type of fish u have though there r several options of great food for most fish. Zuchini if the skin is cut through, peas, par boiled brocholi stems with the skin removed, shrimp, mussels, squid, non-oily fish (preferable feed saltwater fish to freshwater fish & visa versa), insects like crickets, grasshoppers, bees, spiders, earthworms, microworms, beef or turkey heart, small quantities of par boiled pork liver, spirulina algae, other forms of algae & sea weed that can be bought at the grocery store in the sushi section or fresh at most asian markets. My fish r hit or miss on romaine lettuce & spinach though give the peas another try because all of my fish love them. Buy frozen peas, take a handful & run them under water for just a few seconds, piece the skin of the pea with ur thumb nail & squeeze the pea. For smaller fish squoosh one of these pea halfs & soon they will start eating them. For larger fish u can just defrost & throw them into the aquarium. I hope these ideas help.

Depending on the size of your fish there are several options. You can explore live food, frozen foods, and freeze dried food. Most tropical fish will eat brine shrimp which you can raise live or buy frozen. Dried blood worms are also good for most sizes of fish. The best idea is to speak with your local dealer about the type of fish you have, they will be able to point you in the right direction.

They already have enough meaty food in their diet with what you are giving them, which can often lead to constipation. Once a week, try dropping in a thin slice of cucumber. Most fish (except maybe Bettas and Tetras) will love the cucumber and can be observed skimming small bits off of it. My Loaches and Otos love it. Email me if you have any questions.

that is a good diet. most fish in america end up living off of flake food alone anyway. I do not know what else you can give them. they seem to have a pretty solid diet as is. if you have any carnivorous fish, you could raise sea monkeys in a seperate tank and feed the adults to them (sea monkeys are only brine shrimp that grow to about 1/2 an inch.).
