I just introduced my first fish to my first aquarium. I got a couple of clownfish and they both keep swimming against the back of the aquarium, which is black reflective acrylic , as if they are touching their friend (actually their reflection). Is this normal? Will they eventually realize that their reflection isn't an actual fish??
