Here's a video taken today of one of the larger more developed A. arcuatus larvae.
Larval rearing is an ongoing parade of developmental phases and this is my favorite part as the larvae get close to settling out. They will go through their transformation to the juvenile stage with both morphological and behavioral changes. Some of the larvae have started to hangout next to the sides of the tank with their bodies in an S shaped curve. Hopefully we'll start to see some juvenile colors coming in soon.
