Actually, they were fighting I think – apparently they can sometimes get pretty aggressive and territorial. I think that’s what they were at. There seems to be one angel in particular who is quite aggressive and attacks other fish, or tries to. I’ve seen him come up underneath a gourami and try to nip his under-fin. And he tries to nip the other angels, too, and chases them around parts of the tank. I think he has an inferiority complex, because he has shorter whisker-bits than the others.
