Is this normal???

Yep, they're eggs. Fiddler crab larvae need brackish water, if you want the larvae to mature to crabs.
 
WHOOHOOO!!!!!!!!! YAY. Well I have a saltwater tank. Could I catch her and put her in the saltwater tank? I only have 1 3 stripe damsel.
 
Well (Hooked Newbie) I do see my male fiddler crab with her alot. So is this a sign? How long do they carrie the eggs?
 
How do I take care of them? Will the 3 stripe damsel eat them? And what do I feed the babies?
 
The larvae will need to be fed very small foods like plankton and liquid foods. I believe they develop in SG 1.016 and higher, and takes a month before they actually turn into crabs.
 
I'd put the female and whoever's defending her in their own wet/dry SG 1.016 tank w/ just a sponge filter and plan on frequent water changes. Put a little flake through a coffee mill or get a brine shrimp hatching kit for feeding (not that that will do you any good until ~a week has passed).

I don't know how long it takes the eggs to hatch...
 
I'd use a 10 or a 20 if I had one laying about. You can either just mound sand in one end or put it on an incline w/ sand in the higher end and not enough water to cover it. Go small for ease of setup, but plan on pretty frequent water changes - because it's small...

I have no experience in raising crab larvae, but it's what I'd try unless offered a better game plan by someone who actually *knows* what they're talking about.
