Reply to comment by HunterDHunter in How do fishes get into isolated inland lakes in the first place? and why don't we see more divergent evolution / speciation given the separation of each group of fishes from each other? by I-mean-Literally

I know a cave up a hill that's only fed by the drops from its ceiling (which are from hill run off making the cave pretty much a spring) and the cave has little fish living there that people throw food in for.

My guess is birds like you said, or some mischievous humans.

Depending on the source of the cave, it may have been a flooding event, or a water table connection

Interesting speculation. The lake I live on is spring fed. I never thought of fish egg transport through water tables.
