I have 2 hermie huts. One is purple, so I finally caught on that it is just as harmful as painted shells and removed it. Does anyone have a neat little trick to remove the purple from the hut or is it just trash?? Kinda like the shells-boil them to remove the paint. Also, they are always crammed under the one small hut. So much so that the hut is raised off the ground!! So I bought a nice big natural hut for them and not one stinkin' crab will go under it. I put a couple under it and they all go right back under the same small hut!! Why is this? Is there something wrong with the new hut, or do they just need to adjust to it? I boiled it for about 5min before putting it in their home.
