I thought it was some kind of eggs sack this morning now only a few hours looks as though some kind of crab or hermit crab is hatching out of it looks really blue anyone seen this before
Yep after investigation it was a hermit crab with no shell with is really weird since I only purchased 3 and still have 3 also I remember a week ago I noticed blue hermit legs and claws around an area and thought it was a massacre but still had all my hermits do they shed like shrimp
Yep they shed , do you have any spare shells in the tank , if you do place one very near to were he's hole is and he might move in .
Not so sure he'll move about much without he's shell as he's very vulnerable without one
