Is a 20 gallon tank enough for 11 angel fish?

Dead ones.....

A 20 gallon tank is big enough for zero angelfish. Right now, at 2 inches, 11 is already pushing your tank's limits. They get to 6 inches long and will need at least 90 gallons for the angelfish alone... at least 125 if you want any other fish in the tank.

Oh, my. I hope you're joking. Angelfish grow to be about six inches long (not counting fins).

You need a 30-gallon tank or bigger just for a few (3-4) of them.

If you have 11, or 20, in a 20-gallon tank, they will all die until you have only one or two left. Then even that one or two will eventually outgrow your tank.

no! a single angel fish needs 30 gallons. so for 11 you will probably need 100 gallons at the most

Right now the tank is full, but possible. But Angels grow to about 6", plus fins. Just not going to work in a 20gal, even for one.

11 Adult angels is going to need about 120gal.

No Ifs... no buts...
