Most of the angel fish show a dramatic shift in coloration associated with maturity.They are protogynous hermaphrodites ie, if the dominant male of a harem is removed, a female will turn into a functional male.

There is no scientific evidence to suggest that babies can sense if someone is pregnant. Therefore, they do not exhibit any unique behaviors or reactions as a result.
There is an Angelfish.
A anglefish, or even an anglefish cannot have any symmetry because there is no such thing. An angelfish has lateral symmetry (approximately).
Angelfish are not endangered as far as information will tell
I am aware that Angelfish and any kind of Frogs should NEVER be in the same aquarium so I do not know the answer to your question.
They are unique because they are way different from other primates.
No it is not, as you can see, the queen angelfish is much more colourful. The angelfish is just black and white. Except for the male, it is colourful but not as colourful as the queen angelfish.
Angelfish are optomistic omnivores, and may eat very small fish of any kind. If it can fit in the mouth, its not safe.
There are not many fish that are compatible with Angelfish. Only Angelfish are truly compatible with Angelfish.
Angelfish Albino Cory.
Angelfish breathe the same way any fish breathes. They take in water through their gills and take in the oxygen in the water and release the water.
