I have a new betta. I'm enjoying seeing that he is a different fish from my last one.
I've heard of people who have betta fish that can be hand fed or like to be touched. I put a finger tip in the water and he bit it. I later stuck a piece of freeze dried bloodworm to a finger tip and he ate it. My last fish would flash his gills and swim away if I placed a finger in his water.
I was worried that my filter might create too much of a surface current and would agitate him, even though my last fish was fine with it. Earlier he was swimming around the filter, back and forth and playing with the bubbles. I think its a hit with him.
