    Hi Peeps!

    Just a few quick questions regarding hermit crabs

    What hermit crabs are the best to get?
    What Size? Big or small?
    How do you know if a hermit crab is reef safe?
    Does anyone have some nice Pictures of Hermit crabs?
    What shells to get for crabs that need to grow? and if this is the best thing to do?
    Also what snails go well with hermit crabs?
    How many crabs to put in a tank compared to the size of the tank?

    Any info would be much appreciated! :thumbup:

    Hi Sentari - any hermit crab that is of the DWARF kind.
    Please do NOT get the red legged (with white/blue spots) - as they are destructive and NOT reef safe!
    Neither the blue legged (the big one's).

    The blue leg once, are the best they don't bump as much stuff over as the other once.If you can get them take the one's thats about 1.5cm to 2cm.

    Turbo snails are you're best bet.

    Mexican red legged hermits are the safest if you can get them. (they are just red, no spots etc)

    Now The Blue Leg is DEAD.... He was Killed, eaten and his shell taken over by the Red Leg..... Needless to say, the Red Leg is sumped until further notice... He walks over my hammer coral, my zoas and mushrooms and every day I have to replace the hammer, he's not very active as a clean up crew either..... Thats my feeling regarding this hermit....

    I have just sumped my red legged hermit crab, as I caught him attacking both my starfish. If anyone wants him you are more than welcome to come and collect him. (He does need a bigger shell.)

    I got the Electric Blue Hermit and he is pretty cool. Still small and does no damage, that I am aware of, yet.

    @marsbrat
    Is that local or did you get it from LFS.

    If local, it does look like a Blue Eyed Hermit. But claw is the wrong colour. Blue eyed bottom part of big claw is white. And I do not have problems with them. Only issue (if you want to call it that) is that they get to 30mm in size and tends to knock smaller rocks and corals down.

    I got it from a local friend...lol...

    The bottom half of the big claw is white...

    Is it an import or local?

    Also, today I saw this one eat one of his friends...same type..Is this due to me possibly not having extra shells in the tank?

    I then also hear that if a crab has hairy legs then I mustn't take it? More info please?

    Yip, they do end up in fights, for the shell. So they tend to take out your low spiral snails like turbos and nerita's. Eat them out then try to move house. Only to find out then that the new house is too small. So they move back to the old shell.

    So yes, get some extra shells. They would rather use it, that to go into a fight.

    Hairy legs hermits, yeah they are normally the ones that grow and grow and grow. Google Dardanus Megistos for example.

    Here is my local hairy hermit
    [​IMG]
    he grew up to be quite big. The feet across was easily 100mm. Big boy, but ate out of my hand. Knocked everything over. And ended up living in my sump, keeping it nice and clean.

    But sadly, he passed away. Had him almost 2 years. more info
