arrow crab info!?

[protossdisaster]

Has anyone else see the arrow crab open his belly. I dont see to much information on it. I got a video i had to do in black/white because of the intensity of my blues at that time. But check it out.

That's perfectly normal crab behavior. He isn't actually opening his stomach, all crabs have stubby tails curled underneath their bellies. Females use it to carry eggs. He's curling his tail away from the rest of himself in order to clean under it.

Awsome never had any clue he even had that. Do mithrax crabs have that?

All crabs have that, to the best of my knowledge. If you flip a crab over (difficult, they don't like it), you can check. On blue crabs, you can tell the sex by checking the tail- females have a wide tail that they carry the eggs with, males have a tiny pointed tail.

Sounds like turtles xD I have a western painted and a RES that are 10 years old. Anyways how much experiance have you had Betta132. One day i'd like to get into breeding invertabrates. And raising and rearing. I have 7 tanks which includes a breeding pair of bettas xD

Correct tat is how we tell on blue crabs...narrow or wide tail
