Tank raised are wild caught, as free-floating larvae, and then raised in an aquarium. Tank BRED fish were hatched in an aquarium.
There is no benefit to wild caught fish, and many to tank raised/tank bred fish. Wild captured fish are more prone to parasites, and less likely to eat prepared foods initially. However, currently, most often captive bred/raised fish are more expensive, than wild caught. If you can get cpative raised for cheaper, definitely do so! I encourage everyone to go with captive raised fish whenever possible.
