Question on angels with oter cichlids.

[Hadesdrew]

Ok so I got a powdered blue cichlid(Petsmart gave it to me for free because they need to get rid of him) and put him with my 6 angels and 4 black skirt tetras. It's only a 55 gallon and I know that its an african with amazonian fish so the softness is off for him. Other wise he seems to be fine. Angels are slightly bigger except for 2 of them. Am I going to have serious problems?
Angels are around 4", blue is around 2 1/2".

Mbuna are way too rough for angels,is he decides to he will tear them to bits.Also have different dietary requirements.

However I do keep silver dollars with mbuna.More similar diet and the mbuna appear to completely ignore the dollars.So anything is possible.

I agree with Gomez. I would not keep an African with angels.
