I think my guy and gal are both in love with me. I hand feed them bloodworms at least twice a week right off of my finger tip so when they see my finger there is a DEFINITE association with food. It's also pretty neat to feel the nibble your finger lollol
Lol, I can't do that, because Puffy would probably bite my finger off, and Simba would try to jump for it before my finger is anywhere near the water. Feeding my boys bloodworms requires either tweezers or a small eye dropper XD.
