I put this as an emergency because I don’t want my clownfish to die from starvation. I bought a second clownfish 3 days ago to pair with my older one (which is going decent), and every time I feed the frozen mysis, my clown will eat it, then spit it back out. He keeps trying to eat, but every time spits it back out. Does anybody have any ideas, if this is just because he is new?
