Maybe so. These were blue angels, so probably even more so. My new ones are natural color, so hopefully they're from the deeper end of the gene pool.I find domestic angelfishes tend to not live that long - 4 or 5 years seem old for them; probably all the inbreeding screw up their zest for life.
Yes. But they’ve lived together for years in a big group. And his body didn’t show any torn fins or anything (beyond appearing to have been chewed on by snails a bit). So I don’t think it was aggression or fighting. Looked like something internal did him in.Was he in the same tank as any other male angels?
It's possible, but I don't think so. Other than the usual posturing at each other, I haven't seen any real aggression in this tank, even during breeding spells. It's a really big tank, with lots of plants and structure, so they can get away from each other when they need to. They'll take a poke at each other occasionally, but one ends up moving away and there's no chasing or crowding that I've ever seen.probably death by stress, especially if others in the same tank are breeding
Cardinals prefer a larger aquarium with places they can feel safe. I have 25 in a 100 and i feed on both sides of the aquarium and those annoying tetra follow me around when i try to feed the other fishes. Worse when i do water changes i have to push them out of the way when manuvering the python. They just don't know how to go into a back corner and leave me aloneMy dentist recently bought a small aquarium for Paracheirodon axelrodi for his office. It is interesting, but it seems that the fish are stressed and so timid.
