Solo hermit crab?
Hi yall. Question, can a hermit crab be kept alone? Basically I’m visiting family, there’s a big hermit crab tank here and they said all the crabs had died and need to get rid of the tank. I figured okay, lemme be helpful this weekend and go clean it out since there’s like probably 50+ lbs of sand + soil mix in there. I start taking some of the decor items out…. And staring at me is a hermit crab! He wasn’t even buried just hiding kinda underneath a piece of wood. I was like ummm wtf?? So I sifted thru the tank and he’s the only dude in there. I immediately got some water conditioner and added water to the sand + soil since the tank was very dry, got it to like beach sand consistency. Misted the tank, cleaned out the water bowls, got it all setup nice for him and he’s cruising around exploring now. My question is can he live alone? Under no circumstances does my family want anymore pets, so the suggestion of telling them he needs a buddy will not get anywhere. I guess hypothetically I could take him, but that may prove difficult since I live 1,000 miles away and already have 2 dogs, a lizard, and a bird. Tank is 40 gallons, probably 6” of substrate, and lotsa climbing stuff.
