Title: freshwater crab
Post by: Bella on April 02, 2008, 05:39:40 PM
My daughter thinking she was being wonderful to me brought home from the petshop a freshwater crab or that's what they said it was.  They told her it didn't need any special food as it would eat fish food off the bottom.  So anyway she puts it in my 10 gal Q tank so I've been feeding it fish flakes.  One day I look in and see Lucy the crab upside down apparently dead.  I scoop her out she is the size of a dime and throw her in the trash.  2 days later when I have time to clean the Q tank, I find what looks to be a Lucy in the Java moss.  I check the trash actually dig through it and yes there is still crab there.  My stupid question is do crabs shed their whole shell in one piece? if not how did I get two crabs one dead and one alive from one crab?

Help me here do crabs need as long a Q as my other fish?  Are they fresh water?  Will Lucy survive in my 30 gal tropical tank with a dwarf gourami, guppies and cories?  Will the crab eat my other fish?

You will need to find out if it is a fiddler or a red claw, neither are freshwater and will need a brackish tank with a land area in it.  Molts are usually the whole shell, it is common for first time owners to think their crabs are dead. lol

It looks to be a fiddler.

I've placed aquarium salt 1/2 teaspoon to 10 gal.  Will slowly increase the salt.  Crab will stay alone.  I have placed floating plants and a rock so she can get out of the water.

That's a good start!  The crab will need a synthetic marine salt, not aquarium salt though.  Instant Ocean seems to be the cheapest out there and you'll need a hydrometer to measure the salinity. :)

Also, make sure it has access to an area where it can climb out of the water if it wants to. Try lowering the water level and building up the substrate on one side, or something similar.

I did that already but thanks for the information.
