hermit crabs

New to saltwater aquarium hobby. I have a 20 gallon tank fish only. I have had general success with it up to this point (the fish are doing fine). I bought 4 electric blue hermit crabs for a CUC and in the last 2 weeks have lost 3. I also have a cleaner shrimp who has been doing great. My...

Hey y'all! I have a few photos to share of my setup. Added 3 macros today. Currently have a Clown and a flower nem in quarantine tank. Will post those 2 after introduction to display. Display has 1 Royal Gramma, 1 Citron Clown Goby, 1 Condylacti, 1 Bubbletip, 2 colonies of polyps, 1 colony of...

Currently have a 13.5 gallon thats loaded with crabs. I have a halloween hermit crab, 20+ electric orange hermit crab, decorator crabs, pitho crabs, all of which are crabs that don't touch my corals. On the other hand, I put a tiny cross barred venus clam in the sand bed and I later found that...

What is this hermit crab? Is it reef safe? Any information is welcomed! Thank you!

Hey all, Hoping to get some suggestions on what you think the best online sources are for hermits. I am looking to buy 50, and was wondering if there is any difference between sources online. Thanks for help!

Thought I would share some pics of my setup. Added the clowns two weeks ago, and the firefish yesterday. I was thinking of doing one or two more fish in here...

My corals were looking incredible for weeks now and I hadn’t seen any of the hermits in the tank bothering them aside from trampling my zoas while they roamed around...until today. I caught one of the blue legged hermit crabs literally in between the branches of my Garf Bonsai and it looked like...

I'm almost sure that my tiny (maybe red legged) hermit crabs are eating the coralline algae off my rocks. I had some nice purple patches developing on my dry rock and now they're completely white. I noticed last night that three crabs were all clustered around one little dot of purple. Also...

Reason why I'm asking this is because I was told couple different stories all at once. One person said that ONLY blue leg hermit crabs are reef safe Another said that all hermit crabs are reef safe and lastly another person said red leg can be hit or miss All 3 happen to work at the same LFS...

Hi guys, I’m so sad, my hermit crab was switching shells yesterday and this morning I found him out of his shells. He was still moving and trying to get into the shells, but now a couple of hours later he is not moving, he is just laying still on this position. I’m afraid he has died. Can...

Since starting my 24gal Biocube, I have had a total of 10 hermit crabs. I initially had 3 along with a blue tuxedo urchin and two of the crabs died off within a couple of weeks. Then I purchased 7 more along with 5 turbo snails. A couple weeks later we added 3 corals, followed by a Tongan...

Hey guys, so I’ve had 6 hermit crabs in my 20 gallon tank for 2 weeks now, and during the first days they where all right, moving around, doing stuff, but lately they’ve all stop moving and 3 of them have molted, at same time. I find this very strange, they all seem to be alive, but not moving...
