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.
Toenails do grow back, but how well toenails grow back depends upon where they were broken. Nail growth occurs in the lunula, the white half-moon shape at the bottom of the nail.
