Would this work in my tank?

I have a 90 gallon octagon tall aquarium that houses 6 serpae tetras, 6 red/blue columbian tetras, and 6 black skirt tetras.I was thinking about adding 6 angel fish to the tank ( I know they do well in tall tanks and schools of 6). Would this work?
The smaller fish are good, but adding six Angels is too much. You should add four, at the MAXIMUM five. But keep in mind to get only one gender, preferably all females, just so you won’t get surprises. Also, keep an eye on your tetras, they could get a tad aggressive towards the Angelfish. It’s all a matter of the fishes’ personalities.
six angelfish would be too much. however, angel fish are not schooling fish! they just like to be in pairs or groups. so, you could add 2 or 3 angel fish. a pair or 3 angel fish will go well in your 90 gal.
have fish
good luck
Angelfish don’t actually school, they form breeding pairs. There’s no visual difference in the sexes, but from six you should get at least one pair. That’s when all hell will break loose. A breeding pair are territorial and both will attack intruders. The high nature of your tank works for displaying them, but gives the other fish nowhere to escape.
Edit:
Three only works if they are all the same sex. A breeding pair would hunt and kill the third fish.
If you care anything about your tetras then I suggest you do not add angels. They are aggressive and territorial, they would not be a good mix with your tetras.
One angel would do really well. While they can be agressive to smaller fish, the types of tetras that you have shouldn’t be in any danger. Angels prefer small tetras like neons and cardinals as ’snacks’. Since your tank is tall, there’s not really enough room for a group of angels to each have their own areas and avoid each other. I have 4 of them in a 5ft long 150g tank and they still pick at each other occasionally.
I would get two angels instead of 6. Two angels raised together should get along very well, especially if you get two of the same gender. Angels are very compatible with many fish. Angelfish do well with the larger tetras like the black tetras, serpaes, white-tipped, and silver dollars. It is important to remember that angels need space to grow and be at their best. Given a tank with uncrowded conditions, the angel will thrive and grow to its full potential.
