It's about 1.75 to 2" long now, and came from a mixed Jack/Terror tank.
It does not have the tell-tale green stripes by its mouth, but does have the orange/red fringe on the dorsal fin (did not showup in the picture).
It does have the little blue and green jack spots, but not as prolific as one would expect, and also has a brown/black striping over his body.
Jack? Terror? A cross between them?
