PostSubject: Some of the Crab's I keep   Thu Jan 22, 2009 11:33 am

Hi, Im Kevin, from South Wales. I keep a few different species of freshwater invertebrates, mainly crab species. I'll be keeping quite a few more by the summer hopefully. Heres are the species I currently keep,



Potamidae sp. India - I have one adult female of this species, I hope to get more of them in the spring



Cardisoma armatum - I have one of these, he's currently around 18cm or so, and at least 6 years old, possibly much older.



Oziothelphusa or Spiralothelphusa sp - I have one adult male of this species, I should have more this spring though hopefully.



Geosesarma sp. vampire - I have 6 adult crabs, and at least 10 cb juvenile's, probably many more since they burrow and have plenty of hiding places.



Metasesarma aubryi - I have a male/female pair of these, unfortunatly though they are difficult to breed in captivity, as the young need brackish water to develop, though the adults are freshwater and spend most of their time on land.

Do you keep them in separate tanks?
I have a rainbow crab, I used to have two but one died shedding his shell about three years ago. The place where I buy them advised not to put another one in the tank as they fight.

They are kept by species, the Metasesarma aubryi are ok to be kept together, and also the vampire crabs. The two Indian species should also be ok in small groups, but rainbow crabs are territorial and will eventually fight ive found.

affraid wOW, your crabs are amazing!

I didnt know you could breed crabs in captivity! I love the Geosesarma sp. vampire -crabs that you have. What conditions do you provide so that they breed. Do they have a larval stage? How do you rear them? alien

I keep them in a heated, fairly humid tank, 2/3 land, 1/3 water, that is fairly shallow. They have pieces of bogwood and mopani wood to hide amongst. The females carry the eggs, the young are born as tiny crabs.

My Potamidae sp and Oziothelphusa or Spiralothelphusa are also true freshwater, so can be bred in captivity without brackish or saltwater.

I feed my ones mainly crushed aquarian, hikari crab cuisine and crushed sinking catfish pellets. Ive kept them since January last year, apparantly they live several years, but it wouldnt be known yet, since theyve only been kept since around 2007 I think.

Theres some info on them here,

Hi Kevin,
Just wondered if you wanted my Metasesarma aubryi for your collection? I wouldnt want anything for it, just £3.49 for postage. I'm still not sure of its sex. Its healthy and active. If so, please email me ukfish@hotmail.co.uk
Thanks Very Happy
