Have cherry barbs, neons, zebra danios, guppies, pangio loaches.

What I can feed them to increase their variety of diet, be sure to provide enough vitamins, while lesson cost to buy food just for fish? Though cost is NOT my primary concern since fish food is pretty cheap here. More interested in the sufficient variety and vitamins. So regardless of opportunity to use "human" food for the fish, would continue to use fish food most of the time anyway.

Have seen on internet some fish will eat broccolli, cauliflower, lettuce, and green peas. Saw posted here on forum that some aquarists "make their own food mixture" but not written WHAT that is.

Will my fish eat any human food? If yes, what? What do you feed your fish? What self-made mixtures do you use that would also work for my types of fish?

Thanks for your suggestions!
