Emerald Crab problem

[Chewbacca]

My large emerald crab has developed a white spots with holes on the claw shell I have tried looking thru threads on site and elsewhere couldn’t find any thing. Any help with this problem is greatly appreciated. Two photos one shows highlight other without.

Look like Barnacle.

I've never seen that before. If it's a boring insect, it will show up again after the molt. If not, the molt might cure the problem. Keep us posted.

Calcium deposits or barnacle

I have been dosing calcium to raise the ph levels for two weeks at 10 ml per 20 gallon on 100 gallon volume.

Testing for and if needed adding some iodine might encourage it to molt.

My iodine level is currently at 14. High already

14??? or 0.14?

 

[Chewbacca]

Sorry. It .14 the stupid typer hit the decimal in the wrong place

If you look around the internet every emerald with a top down shot has 2 marks where yours are, not as deep. Not sure what it is. I’d wait til he molts and see.

Check out my thread on the same issue. Looks like injury occurrence while new molt/shell still soft. One tank with emeralds at a shop had detached claws laying around and two crabs had the same holes in their claws with the same white/black coloration. It appears they get rough with each other.
