Cichlid ID Please

Greetings

I bought a Cichlid over the weekend that the LFS guy named a "Deacon". Its
almost got the same shape as discus but not quite! It has vertical bands
over the length of its body. Its still a juvenile and colours have not
started coming through yet so its a dirty brown colour at the moment, the
LFS guy tells me that they colour up amazingly and get to about 15 cm long.
Does anyone have a clue what this fish is and can you supply me with a
scientific name? I'll try post pics tomorrow but if anyone knows offhand
from the description given it would be great. Many thanks indeed.
