We have 5 Fiddler crabs, 3 males, 2 females. There is clearly a dominate male that has attracted BOTH female crabs. We saw the male and one female in the act and we could do nothing to separate them (He had a strong hold on her)
So now I believe we have around 200,000 babies floating around in the tank. From what Tom and I read it's extremely hard for the babies to make it in captivity because they need special food and have to be living in the ocean.
We don't have the space to set up another tank for them (we are maxed on all usable space to any sort of set up).
One female did lay her eggs in the water a while ago, and we're still at 5, so i'm hoping that the babies won't make it.
I'm not looking for advice (i.e. Get a seperate) just thought i'd share.
I wonder if you can spay/neuter fiddler crabs...
