I go to the downtown pet store, and the owner tells me he ordered a few fiddlers because I was interested for the mudskipper and they arived. the one with the largest body (1.5"-2") had a claw that was 1 cm or 2 longer than its body, that it was completely hidden by. I reserved him and he will be with the skipper in about a week. I know that they are harmless, and the only perposs of a males claw is to attract a mate. How often are they breed in captivity? how dificulte is it? Also I told the pet store they needed a land water tank. they have a 5 foot by 5 foot tank with 20-30 1" red-eared mudslider turtles (display only), 2-4 fire belly toads, 3 6" waterdragons, and I am not sure but they might have a 2" snappingturtle left but I think it was sold. whould they work there?
