Almost any kind of fish can be grown in, and will likely require, a nursery pond in order to survive the fry stage of growth. Similarly, almost every kind of fish will be removed from the nursery stage at around 3 to 4 inches of length. Some fish take much longer to mature, like koi taking around a month to grow an inch, with other fish like tilapia or catfish growing very quickly.
Some fish will require more maintanence or automation to provide the ideal conditions for. Walleye and catfish are particularly vulnerable to confusion due to reflection from light passing through glass. This causes stress, and can make feeding much harder. If you're growing a different kind of stock, like shrimp, they may prefer unique environments, like extra surface area in the form of baffles or walls in order to gather together and provide shelter.
