I downloaded your code snippet and got the same result - the fish copy's tails are not drawn.
I came up against something similar a little while ago

I was copying a single surface animated B3d that had been set to additive blend (outside of blitz). In that case the copies would often not be drawn or drawn only intermittantly.
D-Grafix mentioned that TED goes through and sets the blend mode for each surface manually (on an imported mesh before making instances).
Seems to me though, that that shouldn't be necessary.
