Ah, **** me in the ***. More of these.
I really am very hesitant to say, but a number of these (the dark ones) look exactly like a group of belo monte fish that I purchased as 333s. I was never given a conclusive ID, but they are certainly of that general line. The others are somewhat ambiguous, and look as though they could be 66 or 400. The eyes are higher on the head for the latter, though, so perhaps that. There are, as you know by now, a number of different animals from B.M. that are exported from altamira as 66, and they come in like this; a mix of potentially different L numbers, or at least, a large variation in a single number.
That's really the best I can give you.
