Larve Description: UNMISTAKEABLE. They have a "rostratum" that is like 10X the length of the rest of their body. There is also a protrusion from the back of the head of sorts. They have big silvery eyes, and the rest of the body kindof hangs down like a shrimp tail... Pictures will do it far better justice
Larval Tank Details Temperature: 82F
Size of Larval Tank: 10 gallon tank, initially half filled with broodstock tank water
Substrate Details: none
Other Tank Decor: none
Filtration Details: none
Lighting: 18" 15 watt strip light
Lighting Cycle: probably was on for around 18 hours per day
Water Changes: none
Larval Feeding Details Food Types: initially, offered nauplii of Tigriops californicus (Tiggerpods). Added in greenwater that included Nanno, Tet, T-Iso and Rhodomonas. Baby Brine shrimp were not already on hand, so it took about 2 days to have those to offer. I dont' recall adding any rotifers at any time, nor did I document any rotifers in my notes.
Feeding Schedule: kinda ad-hoc...was feeding enriched baby brine once I had it twice per day, but they initially didn't go through much if they were even eating it. Only saw actually feeding 7 days after hatch

Originally documented on MOFIB -
http://www.marinebreeder....c.php?f=196&t=2656 Longest I made it was 10 days out...based on the information I had, another crab from this genus was reared in the lab, and well, these guys should be possible. I may try these again...they're fun little crabs and make great additions to a reef tank.
Here's what the parents look like: 
Newly hatched at 10X - look towards the bottom, and notice the extremely long rostratum
Newly hatched at 60X
