Giving them high-protein foods may help induce them into a spawn. It works for some fish, but not all. It also helps give them some added nutrients that they may need to make them healthy enough to breed. I'm not sure if studies have been done on exactly how it all affects different fish, but it's always worth a try. Conditioning the fish you're breeding can also help give you more eggs/healthier fry, etc. Think of it like taking folic acid for humans wanting to conceive. |
