Thanks guanabanus I am delighted to see one person took an interest and a guess.
The first is actually just a tiny brown seeded atemoya that is closer to its cherimoya side.It is bland and a 3 out of 10 in the quality department.It seems to survive only due to it's similarity to the black seeded one in the second picture which is an absolute sensation in the taste department perhaps a 9.5 out of 10.
The intersting thing is that the persistance of the brown seeded mini is dependent on deception and the closer it looks the better and the vendor should also sell for the same price as the real classy mini.
