I was thinking what is good to give my guppies and the others besides industrial food? natural things for example fruits or veggie or I don't know cooked egg, ... I wanna give them a variety of foods. but I don't know what they are. could you help please?
Ive heard zucchini can be good for fish, or even sliced cucumber, if you catch a small insect you can feed that to your fish as well. If you want to buy some stuff for your fish, many will absolutely love frozen blood worms or brine shrimp, blood worms are pretty much pure protein though and should only be fed as an occasional treat.
