“Finch” is a loose term to describe one of many (hundreds!) of small passerine birds. The finch species most commonly kept as pets come from the Estrildidae family of finches, like the zebra finch Gouldian finch, owl finch and society finch. Finches are ideal for those wanting a pet bird but not ready to take on the demands of a parrot. They will be content housed in a large flight cage or aviary with other finches. A finch most likely will not be a cuddly companion (although some hand-raised finches, especially zebra finches, have been known to perch on a finger) like a parrot.
About 5-10% of a pet finch's diet should be bite sized fruits and

Zebra Finches are very hardy birds and almost all illnesses can be traced to improper diet, dirty cages, and drafts. A balanced diet and plenty of exercise will prevent most illnesses. Know your birds and watch for real drastic changes as indications of illness.
Some signs of illness to be aware of are droppings that are not black and white, feathers that are ruffled, lack of appetite, wheezing, and acting feeble and run down.
Some of the common illnesses and injuries your finch could contract are broken wings or legs, cuts and open wounds, overgrown beaks and nails, ingrown feathers, feather picking, confinement cramps in the legs from a cage that is too small, weight loss, heat stroke, shock, concussion, egg binding, diarrhea, mites, colds, baldness, scaly legs, sore eyes, tumors, constipation, and diarrhea.
First you can try and isolate the bird in a hospital cage where you cover all but the front of the cage and add a light bulb or heating pad to keep the interior of the cage at a constant temperature of 85 degrees Fahrenheit. Remove all perches and put food and water dishes on the floor. If you don't see improvements within a few hours, take the bird to an avian veterinarian for diagnosis and treatment. Watch for these if a Pet Finch may be getting sick

Care must be taken when using perches that attach to the cage. I had one pet society finch get her leg/toe stuck in betweenthe cage and the perch. When I found the finch she was hanging upside down in the cage by her toe. She injured herself severely bythrashing around trying to free herself. I thought that she wouldn't survive, but finches are tougher than they appear and thankfullyshe made a full recovery.A finch with a varied diet will usually not need vitamins, however, if you only feed your finch one type of food (such aspackaged finch seeds) then you may need to supplement their diet with bird vitamins available at the pet store. However, you mustbe very careful not to overdose your birds. More vitamins isn't better and may harm your birds.You can find good quality finch food at your pet store. Buy a food that states that it is specifically for finches. You can also supplement their diet with bird treats, such as honey sticks,and also with fruits and vegetables from the grocery store. You can give them foods such as oranges, apples, grapes, cherries, matchstick carrots, and parsley. Be sure the vegetableshave been thoroughly washed before giving them to your birds. Remove any uneaten fruits or vegetables from the cage within a few hours so thatthe food doesn't spoil and make your birds sick. I've even had some pet finches that prefer to take all of the nesting materials and build their own little nest in thebottom corner of the cage floor. The finches that I've had do this have built quite elaborate nests on the cage floor and theyseem very happy in the nest they've made themselves and tend to ignore the store bought nests. For a list of foods that are harmful to finches (and most pets) please see the article .This article also provides tips for getting your finches to eat more foods than just seed.You will find references to 'English', 'German' and 'American' Zebra finches by U.S. breeders. This is not really a reference to their country of origin (although it did originally) or a separate species, but a reference to their size and shape. In Britain and Europe, Zebra finches are bred for competition in shows. These shows have standards that required that the birds display a certain shape and size. Through selective breeding, the size of the Zebra finch has been increased dramatically and the shape has been altered as well. The birds display a more robust and rounded appearance often referred to as 'cobby', which is an English term that has no direct translation other than to say that the animal should appear to have great substance. We still refer to them as English or German Zebras because these are the countries that these show birds were originally imported from. The term American zebra really refers to a zebra that is closer to the wild-type Zebra in terms of size and shape because U.S. breeders did not attempt to alter the physical characteristics through selective breeding. The difference between the names 'German' and 'English here in the U.S. stem back to the size of the original imported stock as well. At that time, the birds imported from Germany were larger than those previously imported from England. The current situation has much of this stock mixed up, though there still appears to be some differences in the birds. I personally have found that stock labeled as 'German', while perhaps being larger than 'English' birds, resulted in offspring that were longer and more 'tubular' than I desired.
