Clarification. This isn't my first baby tilapia. Just the first baby for this season. Rotating stock outdoors for the year usually induces spawning fairly quickly. Not sure due to being in bigger body of water, better food, the lunar cycles, etc. But being outside seems to make them grow faster and breed more. Possibly due to insects, etc supplementing feed sources?
Have noticed it with the prawns as well. Outside always seems to grow faster.
