Angel advice needed quick

Ok long story short. I have a pair of black veils in my 20 gallon High tank. Kids were downstairs playing when one comes up and says so and so broke my tank. So I go down and sure enough it's cracked and leaking. So I took the 2 out and put them in my display Koi angel tank. Now this tank is a 55 gallon tank with 4, ten month old Koi angels in it. I added the 2 blacks to it now, in which their about six months old. So there is a size difference in body size but fin length the veils are longer. Ok can I make this work, 6 angels in my 55 gallon with 5 Cory's for the bottom. I know the story with angels and their temperament and if they pair off and what not. Been keeping angels for a few years now. I just wanted some other people's input on this matter. Also as far as maintenance on this tank it gets two 50% water changes a week. Thanks.

 

Id just watch them closely and see how they do. Theres a good chance you won't have a problem

 

Been watching them and their keeping the black ones cornered. Don't think it will work.

 

I would say that you probably need to get them another tank! If those others have been in there that long, they are not going to appreciate intruders.

 

Try taking the larger ones out and rearranging the tank. Let the little ones set up a territory and then re-add the larger ones. Sometimes this helps but other times not.
