Day 2: Added NHBBS, but they seem to be WAY too big for the hermit larva to eat. Day 3: Moved them to a 10 gallon tank. I added about a gallon of new (aged) saltwater, tetraselmis, rotifers and tisbe. Day 4: Looked at them with a flashlight. Still there. Day 5: Pulled a few to look at under the inverted microscope at work (I actually prefer my microscope at home and look at them nearly every day, but I am having computer issues and can't load my imaging software...so I can't take any pictures)   At this point, I decided that I should probably throw a heater in there...so I did that last night (Day 5) and have been slowly warming the tank up (its probably been sitting at about 72ish degrees F). I also got my hands on a very nifty fish bowl that I might move them to. Its probably two or three gallons and just a sphere with a base--much better for water flow since right now they tend to hang out in the corners. I may do that later this afternoon (Day 6 today) I am trying to learn the names of all the parts, and to recognize zoea stages but its been slow going.

 A tail shot (telson?) from Day 5. Forgot to put it in the last post.

Great photos! I used to regularly catch hermit crab larvae in my snagger when I was trying to catch Orchid Dottyback larvae.
Don't let fear and common sense stop you! =]

Day 7:   I have not been very committed to these guys. They mainly sit in a 2-3 gallon fish bowl, about halfway filled up. I throw in tisbe and rots every once in awhile, live T-Iso or Tet, and sometimes BBS when I have some hatching. Day 9: Changed out about 75% of the water to reduce the rotifer population. There are only like 20 of these guys left (out of the 50 or so that got transferred to the fishbowl from the 10 gallon tank), added some Tet

The eyes also seem more...bulgy for lack of a better word. Or maybe the better word would be "stalked" like I read in one of the hermit crab papers I came across.

Forgive my ignorance, but how long until they reach settlement?

I'm not really sure. I think in some of the threads I read about these, it seemed like a month or so. The few papers I have read are more about describing each stage and don't really say how long it took for each stage. I have started to collect tiny little shells, and took some microscope images with the inverted scope (it has a scale bar) that I will try to post. I'm not sure if they are going to be too small or too big. I feel like my clibanarius larvae are smaller than what I have come across in threads and in papers :/ Still a long way from settlement I would guess though, and unless I step it up, chances are I won't have any make it.

I'm resurrecting this thread since I caught some hermit larvae of unknown species. The are likely blue legs, but I know there are a couple hermits of a different species in a tank plumbed to this system, so I don't want to rule out the other crab. I think they other hermits are C. diguetti or something. I will try to remember to look it up tomorrow. In any case, here are some pics:   I put them in an inverted 3L bottle that has a section cut out and replaced with mesh to allow for water exchange. The bottle is clamped in the broodstock tank for now (about 350-400 gallons total volume) and I gave then some nhbbs. They went all day without food today since I didn't realize I had caught them. I have them moving with a steady bubble using rigid airline tubing.
