Today was bath day since I have to work tomorrow. I bathed Loki with the other three and let them play for about 90 minutes. These crabs have zero interest in each other as far as I can see. Loki did change shells twice and finally settled on the second shell. Loki is still very scared.
When I put them all in the main tank they didn’t all run into their hut and hide for a change…but I redecorated a bit so maybe they like it better 😉
The newbies seem okay… the one crab is still under the sand and the teeny green shell one is still in the same place but not dead.
