crabs in acros

i know there are good crabs and bad crabs,i know the cute tiny white colored ones are acro crabs but what about the fuzzy brown ones w, blue eyes good or bad ,if bad why? i ask because i have had a couple in my acros for some time now i dont think they are causing any problem but i am not totally sure. anyone have any experience w/ these guys?

 

Can you take a pic of them? I would keep close track of them to be safe. I have no idea if they are safe or not.

 

i will try to take a pic but i dont have a macro lense if they are not safe what is it they do do they do damage to the coral or something else any clue

 

They will eat the polyps and any flesh on the skeletons.

 

how do you get them out ? they are quick to withdraw when you get near the coral

 

Tweezers and luck, possibly use a shot glass tipped on edge with some food in it.

 

You can also do a dip like coral rx, but it will kill them.

 

I disagree, the bad crabs laugh at coral RX IME. I just went though this with an acro. Dipped it for 10 minutes, latter noticed a furry, blue eyed crab (not a "good" crab, not necessarily a "really" bad crab). Dipped it again, still there. Looked closer, noticed two babies; all alive and doing fine

 

Well jezzzzz m2434!!!!

Is it iodine I am thinking of?

I am pretty sure it was that or a similar product I used twice and both times I had dead crabs sitting at the bottom, very disappointing.

 

IDK, could be a different dip, or different crab... All I know is I always use coral RX and haven't found any dead crabs. I have found living ones, such as the ones mentioned. Perhaps another did. There is another one, I can't think of the name right now though, that is quite a bit more potent than Coral RX. Or the dose, I know some people use more than recommended, I don't. Just guessing though :-/
