I have purchased some frozen krill for the hermies. I had to go to Petco to find it in my immediate area. My other little pet shops didn't have any. The clerk asked what I was buying it for and when I told him for the hermies, he said they'll love it. (It is worth mentioning that the hermit crab display is taken care of at this Petco. The clerk was so excited to talk about hermit crabs and brought me over to show me the new crabitat they made just for the straws so they wouldn't keep having parties in the main display. They gave them bigger dishes so they couldn't knock them over and dump out their food.) Anyway,as usual, I digress... How often should I serve krill for the hermies? I put one in it's own little shell to serve Bob last night. It was gone by morning. My hubby felt Bob needed it cut into small bite size pieces. Is this necessary? How long can it safely sit in the shell dish if for some reason they don't eat it? How many should be served per hermie? Is there a krill limit? Thank you!!! cj P.S. There was a medium sized crab that looked like it was either white or really light grey. What type of hermie might it have been?
