It started a couple days ago when I was talking to him above the water, as usual. Then I noticed him move his side fins faster to prepare for a jump right at my face and almost completely out of the water. It happened today again; thought he might think my brown hair is his blood worm treat, but then he jumped at my hand when I fed him. Scared the #&@! out of me! Could he be trying to give a kiss or a bite? He seems otherwise normal and happy; bubble nest, too. Please help.
