Yellow perch eggs are unique and easy to collect and hatch. Other fish eggs would be more difficult to collect. With many of the other fish it is easiest to let mother nature hatch them and then work with the fry or larvae. With any fish eggs you can obtain (such as stripping & fertilizing, nest robbing or mat spawning etc.) then hatching with circulating oxygenated water is a possibility. Once hatched basically all fish eat similar items while in the fry/larval stage. When all finage, rays, & spines are developed then food item preferences can change.
