So, I have a crab named "patrica" she will not change shells even though it is WAY too small and is like hanging out, I've had her for over a year and she has NEVER switched shells, but comes far out, so I figure she can't be glued in. Any advice? Thanks.
Make sure you have deep enough water pools, so if that's the case she can allow water in her shell and hopefully over time remove whatever could be sticking her in. But I believe your referring to an E. If so, don't hold your breathe its completely normal and they tend to hold on to their shells for a long time and you will often see Es with too small of a shell.
Keep in mind proper conditions increase the chance of shell changes. I find that when the temp in my tank almost reaches 90*F they are much more willing to jump out of their shells for another.

Like @laceychris92 said, this is probably a compressus. Their bodies & tails are wider but shorter than PPs' bodies so they will heavily modify the inside of the shell to fit-often breaking out the spiral to make room for their tail. Because of all the work it takes, they are loathe to give up these shells. You're likely to see more Es in too-small shells than shells that fit. I have 6 and only 1 (the jumbo) is in a shell that fits right. I have one who was in a painted shell for 3 years before coming to me; it was so small it barely covered his tail. He switched after I got him but not right away. My jumbo was in a shell with a hole in the spiral for well over a year before coming to me. He then kept going after my large straw's turbo so he got put in time-out for 2 weeks. He changed twice in ISO (including going back to the broken shell), then decided on a brown apple land snail shell that he modded. He has changed again The best you can do is to offer lots of choices. I haven't heard of any correlation between temp & shell changes but I'm sure it's possible. Despite having the same sizes available, my PPs didn't change for a while until I added more shells (all the same sizes I already had in there) and then suddenly everyone was changing. Crabs are fickle, silly creatures I think with Es it may also be a matter of knowing that in captivity a snug shell isn't as needed as it is in the wild.
≈19 clypeatus, 4 perlatus & 8 compressus in 4 tanks
In that case, that's rather odd. What types of shells are you offering? and is there plenty to choose from? My PPs are almost never in the same shell as the previous day. I'd recommend turbos, round shell openings are perfect for PPs, but I do have the occasional oddball that chooses 'D' shaped shells.
Temp./humidity need to be at at least 80*F-80% for hermit crabs to properly function.
kitty: Not much activity in my tank. One morning I got up and it looked like a tornado went through it. Water bowls tumbled, food dishes upside down. Fixed it all up and have been waiting eversince. ! Nothing. DARN !!
