Live foods are great for getting hard-to-feed species such as seahorses, pipefish, wrasse, gobies, lionfish, grunts, and newly born sharks to begin feeding.
According to the American Optometric Association (AOA), infants should have their first comprehensive eye exam at 6 months of age. Children then should have additional eye exams at age 3, and just before they enter the first grade  at about age 5 or 6.For school-aged children, the AOA recommends an eye exam every two years if no vision correction is required.hildren who need eyeglasses or contact lenses should be examined annually or as recommended by their optometrist or ophthalmologist. Early eye examinations are crucial to make sure children have normal, healthy vision so they can perform better at schoolwork or play.
Then starting at age 3, they should receive another eye exam. At age 6, kids should have their eyes tested every two years, and more often if their eye doctor recommends it. In general, if you wear glasses or contact lenses, the recommendation is every one to two years. If you don't wear corrective lenses and are healthy and between the ages of 20 and 40, you can get an exam as infrequently as every five years, unless you notice vision changes that may require immediate care.
