Angelfish bully and other sick. I have 4 angelfish. They are all brillant looking. Now, the one I like, the small one, gets chased and picked on by the big yellow-faced angelfish. I don't think he is territorial, but if the small one comes in about 5 - 10 cm of the range of the yellow-faced big angelfish, he strikes. Now, there's a silver angelfish I have that's as big as the yellow-faced one. The yellow-face one doesn't pick on the silver, and the silver doesn't pick on the yellow-face. The silver one usually follows and swims with him, like a school bullies sidekick. The silver one doesn't pick on the small one, only the yellow-face one does. The last angel fish is a black-stripey silver angelfish. He gets picked on by the yellow-face, but not the silver one. The black-stripey silver angel is about 3/4 of the yellow-face's body. So, he tends to hide in the purple weeds, and the yellow-faced one doesn't bother him. But the small angelfish likes to watch me typing at the computer at the glass, so it makes the yellow-faced one get to him easily. What should I do to fix this situation? I'm only 12 hours into the tropical fish life (I bought them 12 hours ago), so I don't want any monkey business or bullying going on. Thanks for any replys. Regards, Brock. Edit : My black striped silver angelfish is sick i think. He hides in the weeds, doesn't move, and breathes fast. What's wrong?!
