There are many similarities between angelfish and goldfish- to name one angelfish and fancy goldfish (especially the oranda) both have several long delicate fins.
Then the goldfish will die.
they both lay egges
One similarity that birds share with most fish, such as goldfish and angelfish, is that they both possess adaptations for efficient movement in their respective environments. Birds have wings that allow them to fly through the air, while fish have fins that enable them to swim in water. Additionally, both groups have streamlined body shapes that reduce resistance and enhance their ability to navigate through their habitats.
the human give birth to young alive while the goldfish lay eggs.
Technically , both require different environments. Goldfish likes cold water and angelfish likes tropical. However, goldfish can survive in warm water so both can be kept, leaving one of them unhappy.
because fish are cannibals

When goldfish are large enough, they are called carp. Tilapia is not a goldfish or a carp, although the species does have some similarity.
One similarity that birds share with most fish, such as goldfish and angelfish, is that both groups are ectothermic at certain life stages. While fish are primarily ectothermic, meaning their body temperature is regulated by the environment, some bird species can exhibit similar behaviors, such as basking in the sun to warm up. Additionally, both birds and fish have evolved specialized respiratory systems—birds have lungs and air sacs for efficient oxygen exchange, while fish use gills to extract oxygen from water.
No, first of all they should not be in the same tank, and secondly, goldfish are egg laying fish so they do not get pregnant
No I'm afraid not. As goldfish grow bigger they eat whatever fits in their mouths. But the only species that mixes with goldfish is the weather loach.
Angelfish are mainly insectivorous and carnivorous. Goldfish are mainly omnivorous and vegetarian. So you can see that their dietry requirements are different. The reason fish food manufacturers have gone to the trouble to develop and manufacture goldfish food as a separate product from other fish foods would indicate that there is a difference in their dietry requirements. So the answer is No! It is not OK.
