The crabs will make sand balls around there burrow. When the tide starts coming up, the crabs will bury themselves into the burrow so only there eyes and antennas are showing. When the tide comes up the sand balls around the burrow will catch phytoplankton, the crabs will pass the sand balls through there mouth and catch the phytoplankton off the sand balls to eat. Because of this people think keeping them is impossible, well I think otherwise.
I thought maybye I could have a rank that's half sand half water. I will pour some phytoplankton into the water, then slowly pour more water in the aquarium so that its like the tides coming up, I will pour more phytoplankton into the water, the sand balls should catch onto the phytoplankton then the crab will do the rest of the work. I will feed in the mourning. I'll then remove half the water 10 minutes later so the tides low again. Do you think its worth a try?
