A: Yes. In the wild, fish get Omega-3 fatty acids (the main nutrient in fish) from eating algae, either by eating smaller fish who eat algae or by eating it directly. In farm-raised fish, algae is added directly as a part of their feed.Sources: Mary Ellen Camire, PhD, CFS, University of Maine.: Yes.

In humans, nails grow at an average rate of 3 mm (0.12 in) a month. Fingernails require three to six months to regrow completely, and toenails require twelve to eighteen months. Actual growth rate is dependent upon age, sex, season, exercise level, diet, and hereditary factors.
An injury to a nail may result in the loss of the nail. As long as the nail bed itself wasn't damaged, a lost nail should eventually grow back. Healthy fingernails grow at a rate of about 0.10mm per day, but toenails are slower, growing at only about one half to one third of a fingernail's rate.
