Hermit crabs disappearing

[crox99]

In the last two monts I lost every single hermit crab in my tank for no reason so I bought 2 weeks 100 blue hermits and as of today they are all gone. Any idea why?

I had a similar problem but i only had about 10 and now i am down to one. Did you rearrange anything in your tank like LR?

 

[crox99]

Mark

Nothing chanced but i don't understand how does the rearranging of the LR has to do with me loosing all my hermits.

 

[marki24]

u sufficating them

 

[crox99]

Anyone?

how old is the tank , maye you got a hitch hicker (octopus) that eats hermit crabs . Get a red light and check your tank when all the lights are out and I mean all the lights even from other rooms

Got wrasse?? Some eat hermits. I'm down to three hermits.

 

[crox99]

I only have a Lubbock's wrasse. Can he be eating them? And 100 in 2 weeks time?

 

[Awibrandy]

JP, it is possible that the lubbock could eat crabs & other ornamental crustaceans. But very unlikely that it is eating 100 of them. I don't even know what took mine out. Especially since thank God, what ever it is that has gotten my hermits has not gone after my shrimps.

The only think that I can think of is a mantis but i never heard any noises from the tank.

 

[Awibrandy]

So are you as neuratic as I can be? I've been known to take my tank apart to find something.LOL Oh yeah, once I emptied out my pond in search of my disapearing catfish, and I mean emptied it totally even the water...LOL

 

[marki24]

I can see you doing that Awilda.

 

[crox99]

I am not going to take the tank apart unless I know the culprit. I don't think it's my water because I use the same water on my 3g and I have 5 hermits and they are still alive. Also I lost recently all of my small fishes (Female lyretail anthias, smaller Lubbock's and a cleaner wrasse).

 

[marki24]

yeah emptying a 120g thats a lot of work. If you need help i am down, i'll wear some baggy pants with large pockets

I'll keep you in mind. Anyone else has any suggestions?

What are your tank parameters? Inverts are very sensitive to tank changes, especially ammonia and salinity.
Is anything else missing from your tank? If shrimp are gone, other crabs are gone, you may have a mantis that only comes out when you're asleep. They really are good sensors of movement.
Do you have any especially large fish? They could be picking at anything that moves.
Do you have enough larger shells for the hermits to molt into? If they don't have another shell to move into when they molt they will probably die.

I HAVE ONE THAT LIKE TO EAT THE SMALL ONE , I WHEN TO SOME AND TOLD THEM WHAT I HAVE SEEN AND THEY SAID THEY HAVE NEVER SEEN THIS, BUT IT COULD HAPPEN BECAUSE THEY TRY TO GET INTO OTHER HOME AND KILL FOR SPACE . HOW BIG IS THE BIGEST ONE AND CHECK HIM OUT . IT WOULD HAVE TO BE DONE IN VERY LITTLE LIGTH THAT HOW I FOUND OUT. EMMANUEL IS RIGTH ABOUT THE LIGTH. YOU CAN SEE A LOT OF THINGS HAPPENING. HOPE THIS CAN HELP . I WAS TOLD TO TAKE HIM OUT OF THE TANK. THIS HAPPEN TO ME i DON'T KNOW IF THIS IS THE SAME WITH YOU BUT JUST HELPING OUT.
