Hi Nicholas,
I don't know what kind of wild angelfish you are looking for. I have 5 altum which I raised from a nickle size since last September. You can search my thread on altum in this forum. Their body size are around 2-3 inches now and 6 inches tall including fin. I can sell you 1 or 2 since they will outgrow my 56g tank very soon. PM me if you are interested.
What wild angels do you have in mind? Most wild angels are much bigger than domestic ones, even the scarlare. If you have a small tank, maybe you can try P. leopodi. They are the smallest, but are very rare.
