Day 45 of the A. arcuatus larval run

Here's a video I just took of two of the larvae. One is the most developed in the group and the other is the least developed. As you can see the larger larva has more black pigment on the dorsal area of the body and if you look closely there is now a little bit of black on it's tail and fins. You can also see the white skunk stripe along the top line of this larva.
The other larvae in the group look pretty much the same as the smaller larva in this video. All of the larvae are showing behavioral changes as they start to associate with pieces of coral rubble and pvc that I've placed on the bottom of the tank.
