first off sorry If this is in the wrong section. I have a 55 gallon saltwater. for some reason my two hermit crabs have died. If you remember my introduction I bought this tank and the tankmates together about 3 months ago. My fish are completely fine and I do about 4-5 gallons a water change every week or so. I don't exactly know my "water parameters" but specific gravity stays at about a 1.023-1.024. I could go get my water tested I suppose if that will help you help me. The owner before had some kind of marine bio. person
come over monthly and check over the tank and help him with whatever need be. Now I cannot afford that. But could something have ate my hermit crabs. I asked my Local fish shop guy and he said maybe I had some kind of worm(s) in my tank? or it could be my iodine is low? He told me to first check and see if maybe the big one moulted, which I thought at first bc there was a sack like thing coming out the back of him. I came back later and that was gone but the "body" part was still there. It's been over a week and It hasn't gone back in its shell and I haven't seen whatever that was coming out of him. I brought the other "body" to the shop and he said that he was dead. I'm NEW
to all of this so I don't know hardly anything at all.
