Hi everyone. My name is mrcrabs and I'm a crabaholic! My daughter came home with her classroom hermies several weeks ago. She was very excited and so was her little brother. In a "last resort" effort of trying to get them to behave one day I told them that they could get their very own hermit crabs. Off to the pet store we go. We came home with a guaranteed death sentence for the two crabs: a plastic critter carrier kit. I had no idea and the fine folks at Petco must not have either. That or they didn't care. Unfortunately, one of the crabs died about a week later. I started doing my research and quickly discovered they never had a chance with the kit the store sold me. I was about to purchase a 10 gallon tank when it dawned on me that I had a 38 gallon in my attic! I have spent the last week cleaning that tank, ordering supplies, visiting just about every pet store in town, searching Lowes and Home Depot for the best sand, a couple of trips to Michaels craft store (I've been there more in the past week than my wife as been in a couple years), drying wet eco earth, etc. :madhouse: The tank is all set... mix of sand and eco earth, salt and fresh water bowls, heat, humidity, etc. So, I go to a different pet store to pick up some new friends for the lone PP who is now living in style. I found a store that carries what I think are Es and I picked 5 that didn't seem too shy. When I put them in the tank, about three of them went crazy and two dug down. After some time, I put the PP in the tank with them. One of the Es started to harass the PP. I thought at first that it could have been a problem with species mixing. I've since learned that it could be due to a number of reasons. In any case, I had several new shells on the way in the mail so I isolated the PP for the night. The next day the shells arrive. I clean them and add them to the tank. The aggressive E pays little attention to the new shells and still goes after the PP. They are roughly the same size. So, I decide to isolate the PP again, this time with several of the new shells. That was good because the PP changed from his painted shell that same night. Whew. I tossed the painted shell and though that would be the end of it. That evening when I got home from work, I put the newly-shelled PP back in the big tank. By this time, the aggressive E had disappeared. Unfortunately, one of the other similarly-sized Es goes straight up to the PP and the cycle starts all over! :BangHead: So, I placed the PP back into isolation and that's where it will stay until I figure out my next step. I do have even more shells in the mail along with some food from the Hermit Crab Patch. The food should have protein and I will also offer them eggs to make sure lack of protein isn't causing the aggressive behavior. If that is the problem, I don't understand why the Es wouldn't attack each other. That's not happening. Only the PP seems to draw the negative attention. Should I add a second, larger PP at the same time I put the bullied one back in? Should I take the PP along with the Es and give them all a bath in a bowl at the same time? Should I make sure they all have a few days with a good protein source in their tanks before putting the PP back in? I'd like to avoid buying another PP if having a single one shouldn't be a problem. I prefer the level of activity I'm seeing by the Es. Any advice you can offer will be greatly appreciated! I'll try to take a few pics of the setup tonight!
