10 gallon Aqueon tank with a 5 gallon drum cut to about 10.25" length to act as a kreisel, sealed with silicone cured for 48 hours. Two windows that are 120 micron nylon mesh of about 4" by 3". Adjustable submersible pump/filter hybrid connected with two feet of 1/2" inner diameter silicone tubing.

4lbs of dry reef rock added with a partially filled aquarium heated currently at 78 degrees Fahrenheit heated with 75W Eheim JAGER heater. Currently it is in the lowest flow. Attempting to cycle with MicroBacter Start before adding in any adult Lybia tessellata.

Order of 6 Lybia c.f. tessellata just arrived today. Buying large groups is often difficult due to their sparse offering and popularity. They are currently being held in the main display tank until the kreisel tank system is finished cycling, which may take more than seven days. None of the new specimens arrived berried, so it will be some time before any potential zoeae can be experimented with. Luckily all of the specimens have anemones on both arms. However, some fighting between the crabs was observed today, this was not the typical fighting seen between two individuals where one lacks anemones as both specimens had two anemones. More information about collection region will be attempted to be gathered from the retailer in order to verify the species with more certainty. It is unlikely they are Lybia edmondsoni since Hawaii collection is very sparse during these times.

Below is two of the 6 specimens obtained today.

Confirmed within an email that the crabs were from the Phillipines, that easily narrows it down to Lybia tessellata. The other species, except for Lybia edmondsoni, are rarely ever offered. I have seen an individual from Japan keep Lybia caestifera, which is very easily distinguished from Lybia tessellata, they may perhaps be offered there in occasion because Lybia caestifera can apparently be found around the waters of East Asia.

You’re trying to breed pom pom crabs?? That’s awesome!!
Yes, it will be quite a long wait before much will happen since the breeding tank still needs to cycle. Also, although mating was observed, it may take some time for the eggs to even be observed since it often requires molting for that to happen for most decapods. There doesn't seem to be much literature on how long it takes for those eggs to mature either, if anyone knows it would be very useful.

@monti mike has a breeding pair of them (post #120 on the crab brag). I don’t believe he is trying to rear the offspring but he probably has quite good information on the time widows from copulation to egg production to hatch.

That would be helpful. Something important to note is that most crabs will actually display their eggs even when they are not fertilized, and will drop them once they start decaying and dying. So egg carrying isn't always indicative of copulation. It would be very interesting to know an approximate time from freshly displayed eggs to when they release their eggs since that would help in figuring out how to cycle through the crabs.
